KDE has released Plasma 6.5.6, the final maintenance update for the 6.5 desktop series. This release marks the end of the 6.5 branch, which launched in October 2025.
Several fixes target the KWin window manager and compositor, including improved color pipeline handling with Night Light, screencast session stability during GPU resets, corrected pointer constraint handling, and refined output configuration logic.
Additional fixes resolve hardware cursor issues on GPUs without modifier support and improve window initialization and attention state handling.
Other core components receive updates as well. KDE Discover now properly handles cancelled backend transactions. The task manager applet includes safeguards for external input affecting progress indicators, and the panel configuration window now maintains focus correctly.
Screen management components such as KScreen and libkscreen receive minor fixes, including improved output size synchronization and better configuration cleanup in Wayland environments. The screen locker now resolves an issue where successful authentication could leave pending PAM jobs unfinished.
Further fixes are included across the Plasma stack. Powerdevil now correctly recreates brightness controllers when display labels change. Device notification handling in Plasma Workspace resolves a dangling reference bug. Spectacle, the screenshot utility, now remembers the “Save As” location between sessions.
Additional minor fixes are included in Plasma Firewall, Plasma Dialer, Plasma Mobile components, the Plasma Welcome tool, and the Oxygen cursor theme.
