The KDE team has released Plasma 6.6.3, the third bugfix update in the Plasma 6.6 series. A significant portion of this update focuses on KWin, KDE’s Wayland compositor. The release addresses several crashes, including a segmentation fault in the zoom plugin and output handling issues.
Additional improvements enhance input handling, screencasting, display management, and support for monitor modes and DDC/CI quirks on specific hardware.
The Discover software center receives several usability fixes, resolving issues with category selection, refresh behavior, and icon consistency.
The Plasma Desktop receives multiple refinements, too. Task Manager tooltips are better aligned, launcher behavior has been adjusted, and several sidebar and panel configuration issues have been resolved. Widgets and applets also benefit from fixes, including improved multi-line tooltip support and more consistent animation handling.
On top of that, the system tray now offers more reliable popup placement on Wayland, and notifications, clipboard handling, and logout behavior have been improved. Font previews in System Settings are now displayed correctly, and various edge cases affecting widget resizing and panel behavior have been addressed.
Power management via Powerdevil has been updated to better synchronize battery state changes, and regressions affecting battery indicators have been reverted. Spectacle, KDE’s screenshot tool, now resolves crashes, graphical inconsistencies, and improves region selection behavior.
Additional updates include improvements to Plasma Mobile, the virtual keyboard, system monitoring, and supporting libraries.
For more details, see the release announcement or check out the full changelog. The next update, Plasma 6.6.4, is scheduled for three weeks from now, on April 7.
