KDE Plasma 6.8.2 maintenance release fixes KWin multi-GPU, Wayland pointer, and desktop regressions

The KDE Project shipped Plasma 6.8.2, the second maintenance update in the 6.8 series, approximately one week after 6.8.1. The release concentrates on KWin, KDE's combined window manager and Wayland compositor, with fixes for EGL copy synchronization failures on multi-GPU configurations, improved buffer type detection, and corrections to direct scanout and DRM color pipeline behavior. Additional compositor work addresses pointer constraints under Wayland, picture-in-picture window stacking order, startup feedback icon sizing, and keyboard layout persistence after an application's final window closes.

Desktop shell components receive parallel fixes: desktop icon disappearance bugs, Task Manager window highlighting and label wrapping errors, Kickoff launcher scrolling and sidebar spacing, Pager desktop labels and window icons, and Activity Switcher sizing and positioning. Wallpaper handling covers animated image tiling, Activity wallpaper cropping behavior, previously unloadable image packages, and solid-color wallpaper accent color selection. Peripheral fixes span KRDP remote desktop session initialization and desktop size negotiation, PipeWire video encoding frame rates and stream dimensions, audio volume feedback theming, Oxygen window decoration button alignment at fractional scaling, Discover firmware update reliability, and PowerDevil battery monitor state switching.

Compositor and desktop shell fixes in Plasma 6.8.2

• KWin multi-GPU/Wayland: Fixes EGL copy synchronization failures on multi-GPU systems, improves buffer type detection, and corrects direct scanout and DRM color pipeline handling.
• Wayland input and window management: Resolves pointer constraint issues, picture-in-picture window stacking behavior, and preserves application keyboard layout after the last window closes; Sticky Keys modifier latching/locking corrected.
• Wallpaper and theming: Restores animated image tiled wallpaper support, switches Activity wallpapers to crop instead of stretch, fixes previously unloadable image wallpaper packages, and corrects accent color selection with solid-color wallpapers.
• Remote desktop and media: KRDP improves session initialization and client-requested desktop size handling; PipeWire video encoding fixes frame rate and stream dimension requests; audio volume feedback now respects the configured sound theme.

Why it matters

Rolling-release distribution users will receive Plasma 6.8.2 as maintainers complete packaging, while fixed-release distributions will incorporate it according to their update policies. The concentrated KWin and Wayland fixes address pain points for multi-GPU workstation users and those running Plasma on Wayland by default, reducing compositor-level regressions that previously drove users back to X11 sessions.
