This page tracks the Wayland showstoppers throughout the stack. Showstoppers are major bugs, crashes, or missing features affecting the Wayland session but not the X11 session. This is part of KDE's [[Goals/Wayland|Wayland goal]].
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 [[Goals/Wayland|Wayland goal]].


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


== Clipboard 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>
* Middle-click-select-and-paste does not work between native Wayland and XWayland apps: https://bugs.kde.org/show_bug.cgi?id=440706
* Selected text in Firefox (wayland native mode) cannot be middle-click-pasted into other apps: https://bugs.kde.org/show_bug.cgi?id=440703
* When "Prevent empty clipboard" is enabled, Plasma sometimes fails to paste text copied from XWayland apps: https://bugs.kde.org/show_bug.cgi?id=424754
* When "Prevent empty clipboard" is disabled, text copied from a GTK app makes it into Klipper, but cannot be pasted after the GTK app quits: https://bugs.kde.org/show_bug.cgi?id=424649
* Can't copy text from notifications: https://bugs.kde.org/show_bug.cgi?id=434675 (very annoying for text messages with a long code you need to enter into a website for 2-factor authentication purposes)


== Window management ==
* No ability to save and restore positions of native Wayland windows: https://bugs.kde.org/show_bug.cgi?id=15329
* No ability to save and restore window content and state of native Wayland windows: https://bugs.kde.org/show_bug.cgi?id=436318
* Real-fake-session-restored apps don't remember which virtual desktop their windows were on: https://bugs.kde.org/show_bug.cgi?id=482816


== Login/Session management ==
== Keyboard/typing ==
* 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 GNOME has —according to [https://wiki.gnome.org/Projects/SessionManagement/GnomeSession their wiki]— an own implementation for some time.
* "Spare Layouts" feature not implemented: https://bugs.kde.org/show_bug.cgi?id=455431 / https://invent.kde.org/plasma/kwin/-/merge_requests/5963
* "Per-application Keyboard Layout" does not work: https://bugs.kde.org/show_bug.cgi?id=476831

* Changes made to cursor theme/size do not take effect in Qt and XWayland software until the session is restarted (takes effect immediately in GTK software though): https://bugs.kde.org/show_bug.cgi?id=420859
* Desktop Grid effect is missing wallpapers: https://bugs.kde.org/show_bug.cgi?id=433071

== Graphic Tablet Support ==
* Wrong mouse is selected for configuration by default: https://bugs.kde.org/show_bug.cgi?id=438266

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]

For example, you can click a button and change the mode from one set of shortcuts like scrolling to another set of shortcuts, like changing hue or zooming in and out.
