KDE Plasma 6.3.6, features numerous bug fixes and enhancements contributed by KDE's team. The update resolves multiple issues, such as enhancing the accessibility of the Discover category, reverting to "discover/qml" for improved updates, rectifying the loss of shortcuts during system updates, ensuring the flickable matches the width of the unwrapped text, and addressing the build compatibility with Qt 6.10. The update additionally resolves concerns related to KScreen, KWin, and Xwayland while also addressing issues with tablet cursor hotspots, Xwayland scaling, and output management.

The Plasma Desktop has been enhanced to incorporate label implicitHeight in frame size calculations, while the Plasma Workspace has been modified to accommodate new locations list URLs and dynamic URLs. The Plasma System Monitor has undergone a partial reversion to prevent the overriding of dialog y: values, and the Plasma Workspace has been updated to accommodate recent changes and display maximized. The update addresses issues with the Colorsapplicator and the Powerdevil app, while also enhancing the Plasma Desktop to support recent changes and display maximized.
