Note that to actually ''drop'' X11 support, even more is needed; see https://invent.kde.org/plasma/kwin/-/issues/202.
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>

* No session restore for native Wayland windows: https://bugs.kde.org/show_bug.cgi?id=436318 / https://invent.kde.org/plasma/kwin/-/issues/113. Our session management recovery 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. Possible workaround: Use Hibernation (Suspend To Disk) instead.
* Picture-in-Picture windows from web browsers get a Task Manager icon and do not stay on top: https://bugs.kde.org/show_bug.cgi?id=463288; requires https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/132 and adoption in apps using PiP windows (like web browsers)
* Calibration/Profiling tools like DisplayCAL and argyllcms are used with [https://en.wikipedia.org/wiki/Tristimulus_colorimeter colorimeters] to ensure monitors are displaying color accurately. A portal (which has not been proposed yet) is required for these tools to be able to calibrate the monitor on Wayland and hand the ICC profile over to the compositor as discussed [https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14#note_2125072 here].

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]
