== Login/Session management ==
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. <ref>[https://blogs.kde.org/2025/11/26/going-all-in-on-a-wayland-future/ Going all-in on a Wayland future]</ref>
* Session restoring does not include Wayland native windows: https://bugs.kde.org/show_bug.cgi?id=436318. Our sessions management recover engine is based on the [https://www.x.org/releases/X11R7.7/doc/libSM/xsmp.html X Session Management Protocol] and there is apparently currently no generic concept to do it on Wayland. But on Qt it's plugin-able and [https://wiki.gnome.org/Projects/SessionManagement/GnomeSession GNOME has had their own implementation] for some time.

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. [1]
