Plasma/Wayland Known Significant Issues

This page tracks the "Errata/Known issues" that are specific to the Plasma Wayland session: significant omissions compared to the X11 session, quality-of-life annoyances, problems with workarounds, etc. This is part of KDE's Wayland goal.

It is the Wayland-specific companion to Plasma/X11 Known Significant Issues.

Dropping X11 session support is tracked at https://invent.kde.org/plasma/kwin/-/issues/202 and is currently planed for the release of Plasma 6.8 . There is no release date for Plasma 6.8, yet. Plasma 6.7 (the last version supporting the X11 session) might get a prolonged bugfix period, but this has not yet been decided.
