<p>KDE Plasma 6.7, the next major release of the popular Linux desktop environment, is now available for Beta testing.</p>
<p>The new version of this free open-source desktop environment introduced many new features with better AMD laptops, and Intel GPUs support.</p>
<p><span id="more-51206"></span></p>
<p><img decoding="async" class="aligncenter size-large wp-image-51207" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/plasma67beta-700x437.webp" alt="" width="610" height="381" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/plasma67beta-700x437.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/plasma67beta-300x187.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/plasma67beta-768x479.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/plasma67beta.webp 1278w" sizes="(max-width: 610px) 100vw, 610px" /></p>
<p>The new desktop version added <b>adaptive backlight management</b> support. It&#8217;s AMD laptops feature that reduces power use by reducing screen backlight brightness and modifying colors in an attempt to preserve readability with the reduced brightness.</p>
<p>For Intel GPUs with i915 or Intel XE drivers, the 6.7 version now enables &#8220;Overlay planes&#8221; feature by default, which improves the video playback and effects performance, as well reduces the power usage.</p>
<p>Besides the hardware specific features, this version also introduced <b>new sliding notifications effect</b> that provides eye candy animation when a notification appears or disappears.</p>
<p>It added <b>dark mode toggle</b> in the brightness indicator, GNOME-style &#8220;background apps&#8221; in system tray, Vietnamese lunar calendar, as well as time zone offsets display (how many hours local time differs from other locations) in Digital Clock widget.</p>

<p>For users who have multiple monitors setup, plasma 6.7 now features <b>per-monitor virtual desktops</b>. With the feature enabled, virtual desktops exist independently on different screens. It supports switching virtual desktops independently for each screen, and, switching desktops via keyboard shortcuts or other methods affects the currently active screen only.</p>

<p>Scrcpy, the popular tool to mirror and control Android screen on your computer or laptop, released new major 4.0 version a few days ago.</p>
<p>The new version of this free open-source application ported from SDL2 to SDL3, added flex display, and many other exciting new features.</p>
<p><span id="more-51199"></span></p>
<div id="attachment_49087" style="width: 620px" class="wp-caption aligncenter"><img loading="lazy" decoding="async" aria-describedby="caption-attachment-49087" class="size-large wp-image-49087" src="https://ubuntuhandbook.org/wp-content/uploads/2025/06/scrcpy-plcm10-700x475.webp" alt="" width="610" height="414" srcset="https://ubuntuhandbook.org/wp-content/uploads/2025/06/scrcpy-plcm10-700x475.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2025/06/scrcpy-plcm10-300x204.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2025/06/scrcpy-plcm10-768x521.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2025/06/scrcpy-plcm10.webp 1154w" sizes="auto, (max-width: 610px) 100vw, 610px" /><p id="caption-attachment-49087" class="wp-caption-text">Android Screen on Ubuntu Desktop</p></div>
<p>First, the new version migrated the backend for video rendering and input handling from SDL2 to SDL3, to benefit from active maintenance, bug fixes, and continued upstream support.</p>
<p>The new SDL3 backend also introduced new features. Previously, it added black borders when resizing (scaling) the Android screen to keep the content aspect ratio. With the new API, the window aspect ratio is preserved while resizing, but without black borders.</p>
<p>Though, if you want, add <code>--no-window-aspect-ratio-lock</code> flag when starting scrcpy to restore the old behavior.</p>
<div id="attachment_51204" style="width: 620px" class="wp-caption aligncenter"><img loading="lazy" decoding="async" aria-describedby="caption-attachment-51204" class="size-large wp-image-51204" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/scrcpy4-noborders-700x555.webp" alt="" width="610" height="484" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/scrcpy4-noborders-700x555.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/scrcpy4-noborders-300x238.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/scrcpy4-noborders-768x609.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/scrcpy4-noborders.webp 897w" sizes="auto, (max-width: 610px) 100vw, 610px" /><p id="caption-attachment-51204" class="wp-caption-text">now black borders by default when scaling, but with option to restore</p></div>
<p>Scrcpy 3.0 introduced a virtual display feature, allowing to start an app silently in your Android then mirror to PC desktop. So you can play Android games on PC, while the physical Android screen is not affected at the same time.</p>
<p>With version 4.0, you can now <b>resize the virtual display window just like a native PC software window</b>. Meaning that you can run Android app or game on PC with custom size that you like.</p>
<p>To enable this feature, start scrcpy with either <code>-x</code> or <code>--flex-display</code> option, along with <code>--new-display</code> which starts a virtual display.</p>
<p>For example, run the command below to start the Android&#8217;s Firefox via virtual display on PC screen with re-sizable support.</p>
<pre>scrcpy --new-display --flex-display --start-app=org.mozilla.firefox</pre>
<p>The resizing may contain glitches, and it preserves the DPI, which is default to 160. Though, you can set custom DPI by <code>--new-display=1920x1080/240</code> option when starting the virtual display, and, increase the bit-rate and change the codec for better quality on large window:</p>
<pre>scrcpy --new-display=1920x1080/240 --flex-display --video-codec=h265 -b16M</pre>
<div id="attachment_51202" style="width: 620px" class="wp-caption aligncenter"><img loading="lazy" decoding="async" aria-describedby="caption-attachment-51202" class="size-large wp-image-51202" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/resize-androidscreen-700x441.webp" alt="" width="610" height="384" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/resize-androidscreen-700x441.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/resize-androidscreen-300x189.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/resize-androidscreen-768x484.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/resize-androidscreen.webp 1430w" sizes="auto, (max-width: 610px) 100vw, 610px" /><p id="caption-attachment-51202" class="wp-caption-text">Android Virtual Display is resizable</p></div>
<p>Scrcpy 4.0 also <b>added more controls for your Android&#8217;s camera.</b> You may use <code>--camera-torch</code> option to start Android screen mirroring with camera torch on, and/or use <code>--camera-zoom=1.5</code> option to set camera zoom level.</p>
<p>Or, use <code>MOD</code> + <code>t</code> key combination to turn on camera torch dynamically and use <code>MOD</code> + <code>Shift</code> + <code>t</code> to disable it. And, use <code>MOD</code> + <code>Up/Down</code> arrows to zoom in/out.</p>
<p>It as well introduced new <code>--keep-active</code> option to prevent screen from turning off due to idle by simulating user activity.</p>
<p>Other changes in Scrcpy 4.0 include:</p>
<ul>
<li>New background color command option.</li>
<li>Show a disconnected icon for 2 seconds when connection lost.</li>
<li>Add F11 full-screen shortcut.</li>
<li>Add <code>Mod</code> + <code>q</code> quit shortcut.</li>
<li>New option to configure the minimum video size alignment.</li>
<li>New option to configure how the rendering fits the window.</li>
</ul>

<p>As you may know, Linux has several ways (VA-API, VDPAU, AMF, NVDEC, or Vulkan Video) for decoding video content with GPU hardware acceleration. Firefox, the most popular and default browser in many Linux Distributions, however only supports VA-API so far in Linux.</p>
<p>Both Intel and AMD GPUs support VA-API, but NVIDIA does NOT. If you&#8217;re Firefox user but running Linux on computer with NVIDIA GPU, then the web content will be always decoded by your CPU by default.</p>
<p>To workaround the issue, the free open-source <a href="https://github.com/elFarto/nvidia-vaapi-driver" target="_blank" rel="noopener">NVIDIA VA-API driver</a> was born.</p>
<h3>JPEG Decoding support</h3>
<p>The driver previously supports for decoding AV1, H.264, HEVC, VP8, VP9, MPEG-2, VC-1 codecs. With the new 0.0.17, <b>JPEG decoding is also supported</b>.</p>
<p>The JPEG codec was previously unusable due to a structural mismatch. VI-API outputs decoded data as separate buffers (e.g., picture params, quantization tables, Huffman tables, slice params/data), but NVIDIA NVDEC expects a fully formed JPEG bitstream.</p>
<p>To fix this mismatch, NVIDIA VA-API driver since 0.0.17 now creates smallest valid JPEG file that conforms to the JFIF standard, directly from the VA-API buffers, before handing it off to NVDEC.</p>
<p>According to the <a href="https://github.com/elFarto/nvidia-vaapi-driver/pull/422" target="_blank" rel="noopener">feature request</a>, the results are exactly identical at the byte level and hash-verified compare to the decoding outputs using the native NVDEC (CUDA). Though there are few limitations (see the previous link).</p>
<h3>Fix for DGX Spark</h3>
<p>NVIDIA DGX Spark, the desktop AI supercomputer, uses unified system memory shared between the CPU and GPU rather than discrete VRAM.</p>
<p>NVIDIA VA-API driver will now check twice during initialization to make sure it&#8217;s running on NVIDIA device with discrete VRAM or unified memory.</p>
<p>When unified memory is detected, it will remember the detection result, add required dependencies from open-gpu-kernel-modules, and use the correct new method to allocate memory. Thus, it will work properly on DGX Spark with Firefox.</p>

<p>Audacious, the lightweight music player with both Qt and GTK UI, announced the Beta for next 4.6 version yesterday.</p>
<p>The new version of this free open-source player app added built-in file browser, macOS Now Playing, other new features and various bug-fixes.</p>
<p><span id="more-51182"></span></p>
<p>First, the new version <b>introduced a built-in file browser</b>, which can be enabled by going to File -&gt; Settings -&gt; Plugins -&gt; General.</p>
<p>It allows to browse or search supported music files in your local computer, then either drag&#8217;n&#8217;drop into playlist, or use right-click menu options to play, add to (or create) playlist.</p>
<div id="attachment_51183" style="width: 620px" class="wp-caption aligncenter"><img loading="lazy" decoding="async" aria-describedby="caption-attachment-51183" class="size-large wp-image-51183" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious-filebrowser-700x435.webp" alt="" width="610" height="379" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious-filebrowser-700x435.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious-filebrowser-300x186.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious-filebrowser-768x477.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious-filebrowser.webp 1313w" sizes="auto, (max-width: 610px) 100vw, 610px" /><p id="caption-attachment-51183" class="wp-caption-text">Audacious Qt UI with file browser plugin enabled</p></div>
<p>The built-in file browser is useful for users, who have a large mount of music files, to quickly find out what you want to play and/or manage playlists. </p>
<p>Thanks to <i>Thomas</i>, GTK users may right-click below the title bar to get the menu to dock the file-manager into main window.</p>
<p><img loading="lazy" decoding="async" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious46-gtkdock-700x573.webp" alt="" width="610" height="499" class="aligncenter size-large wp-image-51205" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious46-gtkdock-700x573.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious46-gtkdock-300x246.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious46-gtkdock-768x629.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious46-gtkdock.webp 834w" sizes="auto, (max-width: 610px) 100vw, 610px" /></p>
<p>The Winamp classic interface still requires windowing system features that are not supported in Wayland. So for Ubuntu, Fedora Workstaion, and other Linux running Wayland session, the <b>Winamp UI will default to XWayland</b> compatibility mode.</p>
<p>And, a toggle option is added to <i>Advanced</i> settings page, allowing user to easily disable XWayland when trying to switch to GTK or QT user interface.</p>
<div id="attachment_51185" style="width: 700px" class="wp-caption aligncenter"><img loading="lazy" decoding="async" aria-describedby="caption-attachment-51185" class="size-full wp-image-51185" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious-winamp.webp" alt="" width="690" height="553" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious-winamp.webp 690w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/audacious-winamp-300x240.webp 300w" sizes="auto, (max-width: 690px) 100vw, 690px" /><p id="caption-attachment-51185" class="wp-caption-text">Winamp UI defaults to XWayland on Wayland session.</p></div>
<p>Audacious 4.6 Beta also updated its UI with <b>Bitrate</b>, <b>File Created/Modified</b> dates support in playlist, though user needs to enable them manually from Appearance settings page.</p>
<p>It added the <i>Playback History plugin</i> for GTK UI, and a setting option to re-enable the confirm dialog for users who checked &#8220;Don&#8217;t ask again&#8221; in Remove Playlist dialog.</p>
<p>It as well added support for <b>.mpc</b> Musepack audio file, support for all AIFF file extensions (<code>.aif</code>, <code>.aifc</code>, <code>.aiff</code>) and MIME types (<code>audio/aiff</code> and <code>audio/x-aiff</code>), and support for reading lyrics tag from Opus, Ogg Vorbis and FLAC files.</p>
<div id="attachment_51186" style="width: 620px" class="wp-caption aligncenter"><img loading="lazy" decoding="async" aria-describedby="caption-attachment-51186" class="size-large wp-image-51186" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/newplaylist-columns-700x501.webp" alt="" width="610" height="437" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/newplaylist-columns-700x501.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/newplaylist-columns-300x215.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/newplaylist-columns-768x549.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/newplaylist-columns.webp 1026w" sizes="auto, (max-width: 610px) 100vw, 610px" /><p id="caption-attachment-51186" class="wp-caption-text">New playlist columns available</p></div>
<p>For users who prefer using keyboard shortcut, the release added global hotkeys support for <code>previous/next album</code> action, and support using <code>Delete</code> and <code>F2</code> keys in Playlist Manager dialog.</p>
<p>And for macOS users, Audacious 4.6 beta added <b>macOS Now Playing plugin</b> for monitoring and controlling audio playback in the Control Center or Menu Bar. And, it removed the Mac Media Keys plugin.</p>
<p>Other changes include:</p>
<ul>
<li>Drag&#8217;n&#8217;drop into Qt winamp UI support.</li>
<li>Read ReplayGain tags with FFmpeg plugin, meaning more files support.</li>
<li>Allow using <i>Previous</i> control to go to the last track in playlist for Repeat mode.</li>
<li>Support exporting playlist via audtool CLI tool.</li>
<li>Use localized music directory for Search Tool.</li>
<li>Load companion .m3u/.m3u8 with Game Console Music Decoder for subsong metadata.</li>
</ul>
<p>There are as well many bug-fixes, removal of deprecated Audacious code and APIs, and more.</p>

<p>FFmpeg, the popular multimedia library, released new 8.1.1 version few days ago.</p>
<p>This is a maintenance release that includes mostly bug-fixes, stability improvements, as well as few minor new features.</p>
<p><span id="more-51170"></span></p>
<p><img loading="lazy" decoding="async" class="aligncenter size-large wp-image-51171" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/ffmpeg811-about-700x466.webp" alt="" width="610" height="406" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/ffmpeg811-about-700x466.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/ffmpeg811-about-300x200.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/ffmpeg811-about-768x511.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/ffmpeg811-about.webp 837w" sizes="auto, (max-width: 610px) 100vw, 610px" /></p>
<p>FFmpeg 8.1.1 updated the ALS decoder for MPEG‑4 ALS audio streams with patch to preserve the full floating‑point value so the decoded audio is accurate and truly lossless.</p>
<p>It ensures nbits is always valid, preventing mis-decoding and potential crashes, and, ensures <code>read_diff_float_data()</code> errors is properly returned by <code>read_frame_data()</code> instead of being ignored, making the decoder safer and more reliable. As well, it fixed the logic for mantissa unpacking in compressed Part A path.</p>
<p>The release added the missing parts of OTTs band phase reconstruction and residual band computation to the USAC/xHE‑AAC decoder, and, fixed an out-of-bounds memoery access for this decoder.</p>

<p>To prevent crashes, corrupted outputs, and/or security issues, it added a safety check to ensure nb_samples is valid in the DFPWM decoder, added a missing return after an error log in the RALF (RealAudio Lossless Format) audio decoder, and, fixed a use‑after‑free bug in the RASC decoder’s <code>decode_move()</code> function.</p>
<p>It as well cleared invalid/stale pointers from the H.264 reference lists, fixed a bug where the H.264/H.265 SEI parser used provider_code before initializing it, and, improved the input‑buffer size validation in TDSC decoder which also improve the stability.</p>
<p>Other codec changes include fix for signed integer overflow in the Nintendo 64 ADPCM decoder, safety bug fix in the ZMBV (Zip Motion Block Video) decodeer to prevent memory corruption, missing padding bytes added to the WMA (Windows Media Audio) encoder&#8217;s extradata to fix compatibility issues, and fix for a memory leak in the VP9 codec‑bitstream (CBS) parser.</p>
<p>Besides fixes for the encoders and decoders, the new 8.1.1 also has many improvements to the <code>libavformat</code> library for container, demuxer, and muxer handling.</p>
<p>It added a maximum size limit to MOV/MP4 demuxer when parsing the lhvc box inside <code>mov_read_lhvc()</code>, added checks to ensure the extradata is valid before accessing it with <code>mov_read_dops()</code> function. And, the demuxer now rejects <code>dimg</code> box references that contain zero entries.</p>
<p>It as well added LIST chunk size and INFO list size validation before parsing for AVI demuxer, fixed potential out‑of‑bounds read in the RTSP demuxer, and, added sanity check to the RTP decoder for QDM2 audio to ensure that the block_size value extracted from incoming RTP packets is valid, sanity check to the JPEG‑over‑RTP decoder to ensure that the quantization table length (qtable_len) is valid, validation check to the MPEG‑4 RTP decoder to ensure that AU Header Sections (Access Unit headers) are not zero‑length.</p>
<p>For libavfilter, it added a minimum input‑height check to the kerndeint video filter, fixed logic bug caused by incorrect operator precedence in the v360 filter, and incorrect handling of <code>sscanf()</code> return values inside the af_pan filter.</p>
<p>There are as well dozens of other changes. See the Changelog file in source tarball for details.</p>

<p>Inkscape, the free open-source vector graphics editor, released new 1.4.4 version for Linux, Windows, and macOS users.</p>
<p>The new version of this GTK application introduced various stability fixes, some new features, and performance improvements.</p>
<p><span id="more-51144"></span></p>
<p>First, Inkscape 1.4.4 is a bridge release that:</p>
<blockquote><p><i>Inkscape 1.4.4 is also a bridge release in the sense that it can be used to convert the planned Inkscape 1.5 multipage file format to the pre-1.5 multipage format. Versions lower than Inkscape 1.4.3 will not be able to interpret pages created in Inkscape versions 1.5 and upwards.</i></p></blockquote>
<p>The new features include <b>new tool option for Star / Polygon Tool</b> to rotate the selected star or polygon into an upright position, and, a <b>new palette for the colors used by elementary OS</b>.</p>
<p><a href="https://ubuntuhandbook.org/wp-content/uploads/2026/05/inkscape144-eos.webp"><img loading="lazy" decoding="async" class="aligncenter size-large wp-image-51145" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/inkscape144-eos-700x413.webp" alt="" width="610" height="360" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/inkscape144-eos-700x413.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/inkscape144-eos-300x177.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/inkscape144-eos-768x453.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/inkscape144-eos-1320x779.webp 1320w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/inkscape144-eos.webp 1526w" sizes="auto, (max-width: 610px) 100vw, 610px" /></a></p>
<p>Besides the new features, the new version also introduced some performance boosts. Zooming in on a document with lots of paths, copy&#8217;n&#8217;pasting large numbers of objects with gradients, opening the dialog with many objects selected, and selecting paths with the Object Properties dialog open are now much faster!</p>
<p>As well, editing gradients with the Gradient Tool is faster now, because the editor does no longer continuously update the tool controls bar anymore.</p>
<p>The new 1.4.4 version also fixed various issues. Up / Down arrow keys can now navigate between objects in layer and object panel. The expander arrows now clickable in RTL (Right to Left) languages. And, text rendering now respects the language metadata (<code>xml:lang</code>)for each <code>tspan</code> separately, instead of using the last <code>tspan</code>&#8216;s language setting for the whole text.</p>
<p>It as well fixed 20 crashes issues, such as crash when starting app with multi-entries for the same file in recent list, starting app with a graphics tablet plugged in, trying to open SVG file with broken markers, and various other cases.</p>
<p>Other changes in Inkscape 1.4.4 in include:</p>
<ul>
<li>Add ability to keyboard shortcut for Paste on page.</li>
<li>No longer open a terminal window for Windows on ARM.</li>
<li>Add <code>libuemf</code> submodule.</li>
<li>And translation updates.</li>
</ul>
<p>This version also includes some known issues, see the <a href="https://inkscape.org/doc/release_notes/1.4.4/Inkscape_1.4.4.html" target="_blank" rel="noopener">release note</a> page for details.</p>
<h3>How to Install Inkscape 1.4.4</h3>
<p>Inkscape provides official packages for Linux, Windows, and macOS, which are available to download via the link below:</p>

<p>Thankfully, Alexander Vanhee, a member of <a href="https://foundation.gnome.org/membership" target="_blank" rel="noopener">GNOME Foundation</a>, make an extension few months ago that enhances the built-in screenshot tool with long requested features before GNOME supports them officially.</p>
<p>It&#8217;s <a href="https://github.com/AlexanderVanhee/gradia-capture" target="_blank" rel="noopener">Gradia Capture</a>, an extension that adds <b>on-screen annotating support</b> when you trying to capture a selection of screen area. As you see in the screenshot above, the annotation supports free-hand tool, rectangle, text, highlighter, arrow, and number stamp tools with different colors, undo, reset support.</p>
<p>Besides annotation support, it also allows you to <b>change the file format between PNG, WebP, and AVIF</b>, configure whether to capture parent windows when a transient window (e.g., Nautilus context menu) is selected, play sound or not.</p>
<p>And, it adds keyboard shortcuts support for actions, such as switch selection mode,  copy to clipboard, and toggle pointer visibility, as well as annotation tools, and system keybindings.</p>
<p><img loading="lazy" decoding="async" class="aligncenter size-full wp-image-51132" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/annotation-prefs.webp" alt="" width="690" height="626" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/annotation-prefs.webp 690w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/annotation-prefs-300x272.webp 300w" sizes="auto, (max-width: 690px) 100vw, 690px" /></p>
<p>As you see in the screenshot, after installed the popular Gradia annotator tool, it can also <b>extract text from your selected screen area</b> using the installed OCR models.</p>
<p><a href="https://ubuntuhandbook.org/wp-content/uploads/2026/05/screenshot-ocr.webp"><img loading="lazy" decoding="async" class="aligncenter size-large wp-image-51133" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/screenshot-ocr-700x290.webp" alt="" width="610" height="253" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/screenshot-ocr-700x290.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/screenshot-ocr-300x124.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/screenshot-ocr-768x318.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/screenshot-ocr-1536x636.webp 1536w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/screenshot-ocr-1320x546.webp 1320w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/screenshot-ocr.webp 1575w" sizes="auto, (max-width: 610px) 100vw, 610px" /></a></p>
<p>Other features include:</p>
<ul>
<li><b>Save to custom location</b> (Ctrl+S to open save as dialog).</li>
<li>Support &#8220;<b>disable initial selection</b>&#8221; when you trigger the screenshot tool.</li>
<li>Button to <b>open screenshot in Gradia</b> for further editing support.</li>
<li>Button to <b>open screenshot folder</b>.</li>
</ul>
<p>As a new project, it will probably add more new features, such as <i>blur tool</i> to hide sensitive data. And, you can request features by going to the <a href="https://github.com/AlexanderVanhee/gradia-capture/pulls" target="_blank" rel="noopener">project page</a>.</p>

<p>qBittorrent, the popular Qt BitTorrent application, released new major 5.2.0 version yesterday.</p>
<p>The new version of this free open-source app introduced many improvements to its Qt UI and Web UI, optimized search engine support, and fixed various issues.</p>
<p><span id="more-51123"></span></p>
<p>First, the new version exchanged the &#8220;Add Torrent File&#8221; and &#8220;Add Torrent Link&#8221; button, so the plus icon goes first in the tool-bar. And, it added &#8220;Torrent Creator&#8221; tool-bar button, allowing users to quickly open the dialog for sharing files with others.</p>
<p>It also ability to <b>display free disk space</b> in the bottom status bar in both QT and Web UI, allowing to glance at how much free space left in your operating system. Though, the feature is not enabled by default, and user can go to Preferences -&gt; Behavior to enable it.</p>
<p><a href="https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit520.webp"><img loading="lazy" decoding="async" class="aligncenter size-large wp-image-51124" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit520-700x443.webp" alt="" width="610" height="386" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit520-700x443.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit520-300x190.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit520-768x485.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit520.webp 1207w" sizes="auto, (max-width: 610px) 100vw, 610px" /></a></p>
<p>qBittorrent 5.2.0 now allows to configure style and color scheme on all supported platforms. User may go to Preference -&gt; Behavior -&gt; Interface setting page to select an app style (e.g., System, Fusion, Windows) and color scheme (light, dark, for follow system color).</p>
<p>For users who prefer custom colors, the colors of progress bar and pieces bar are now customizable, though it may not work in some desktops. And, it added options to disable torrent state colors, and, make progress bar to follow torrent state color.</p>
<p><a href="https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit-colorscheme.webp"><img loading="lazy" decoding="async" class="aligncenter size-large wp-image-51125" src="https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit-colorscheme-700x475.webp" alt="" width="610" height="414" srcset="https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit-colorscheme-700x475.webp 700w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit-colorscheme-300x204.webp 300w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit-colorscheme-768x522.webp 768w, https://ubuntuhandbook.org/wp-content/uploads/2026/05/qbit-colorscheme.webp 1103w" sizes="auto, (max-width: 610px) 100vw, 610px" /></a></p>
<p>Besides UI changes, the new version also implemented a <b>new separate &#8220;Tracker Status&#8221; filter</b>. Enable the feature will add a new category in the left sidebar that groups torrents by the status of their trackers.</p>
