KDE Plasma 6.3.5, a bugfix release for May, features numerous enhancements and corrections contributed by KDE's team. The release features bug fixes for Kcursorgen, incorporates the QDebug feature, and resolves the issue with the "Still Looking" indicator in applications. Furthermore, it tackles concerns related to the KScreen, Osd, Kcm, and various other Plasma addons.

The update also resolves issues related to the rendering loop, backends/drm, effect/offscreeneffect, as well as input and output configuration store. It also addresses race conditions, colorspace, and the association of X11Window.

The Plasma Desktop has undergone an update to transition timer objects from adjustable-duration intervals, resolve issues with the task manager, and enhance padding elements. The Plasma Dialer has been updated to prevent the tracking of the same voice call object multiple times, and enhancements have been made to the Plasma Workspace.

Powerdevil has been updated to eliminate crashes when utilizing PowerDevil 6.3 alongside Kwin 6.2. The print manager has been enhanced to enable the option to set as default when adding a printer or group. Furthermore, Kcm has been excluded from the qqc2-breeze-style package.
