This page tracks the Wayland showstoppers throughout the stack. Showstoppers are major bugs, 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]].


== Login/Session management ==
It is the Wayland-specific companion to [[Plasma/X11 Known Significant Issues]].
* Applications don't prompt to save unsaved work, causing data loss: https://bugs.kde.org/show_bug.cgi?id=461176
* 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.
* Windows that *are* session-restored go on the wrong virtual desktops: https://bugs.kde.org/show_bug.cgi?id=421870
* Session-ending actions don't work after kwin_wayland had to restart for any reason: https://bugs.kde.org/show_bug.cgi?id=449948


== KWin/compositing/window 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>
* When the compositor crashes or restarts, all apps are killed — work is ongoing to fix this, see https://invent.kde.org/plasma/kwin/-/wikis/Restarting
* In multi-monitor setups with at least one scaled display, Plasma context menus have items which are invisible until hovered: https://bugs.kde.org/show_bug.cgi?id=432264
* Task Manager window thumbnails are sometimes all black: https://bugs.kde.org/show_bug.cgi?id=455021
* Poor performance on weak integrated GPUs: https://bugs.kde.org/show_bug.cgi?id=452119
* Blur glitches with GPUs that don't support hardware cursors: https://bugs.kde.org/show_bug.cgi?id=455526
* Sticky keys do not work: https://bugs.kde.org/show_bug.cgi?id=444335
* Monitor connector names are different across X11 and Wayland, so logging into a Wayland session from X11 breaks various KScreen settings: https://bugs.kde.org/show_bug.cgi?id=429236
* Activation issues in KDE apps: https://bugs.kde.org/show_bug.cgi?id=460318


== Plasma ==
== Window management ==
* Saving and restoring activities does not work
* No ability to save and restore positions of native Wayland windows: https://bugs.kde.org/show_bug.cgi?id=15329
* Monitor connector names are different across X11 and Wayland, so logging into a Wayland session from X11 breaks Plasma containment configs: https://bugs.kde.org/show_bug.cgi?id=385135
* No ability to save and restore window content and state of native Wayland windows: https://bugs.kde.org/show_bug.cgi?id=436318
* When using scaling, logging into Wayland session after X11 session resets scale to 1: https://bugs.kde.org/show_bug.cgi?id=433460
* Real-fake-session-restored apps don't remember which virtual desktop their windows were on: https://bugs.kde.org/show_bug.cgi?id=482816
* XEmbedSNIProxy window eats input in top-left pixel of the screen: https://bugs.kde.org/show_bug.cgi?id=433079

* KDE app windows activated by Electron apps don't get brought forward due to lack of support for the Activation protocol in the toolkit: https://github.com/electron/electron/issues/30912
* Lack of virtual keyboard that emulates a hardware keyboard
* In native Wayland mode, Firefox has an invisible animation that forces the screen to constantly repaint, spiking kwin_wayland's CPU use: https://bugzilla.mozilla.org/show_bug.cgi?id=1754810. Workaround: set 'widget.wayland.vsync.enabled' to 'false' on its about:config page
* Installed Chrome apps do not show up as a unique app but instead assume the Chrome icon, in Icon-Only Task Manager: https://bugs.kde.org/show_bug.cgi?id=358277

== Graphic Tablet Support ==
* KDE app windows don't get brought forward when activated by another KDE app: https://codereview.qt-project.org/c/qt/qtwayland/+/321246; fixed in Qt 6.2
* Some tablets allow users to switch between touch strip modes. 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. This is not possible on Plasma Wayland: https://bugs.kde.org/show_bug.cgi?id=477787

== Fixed in an upcoming version ==
* Sub-menus are mis-positioned when parent menu is close to a screen edge: https://bugs.kde.org/show_bug.cgi?id=500584 / https://bugreports.qt.io/browse/QTBUG-124810 - fixed in Qt 6.11

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]

Window management

Keyboard/typing

Screens

  • No way to change the gamma or manually adjust the colors without generating or finding an appropriate ICC profile

Accessibility

  • Lack of virtual keyboard that emulates a hardware keyboard

Graphic Tablet Support

  • Some tablets allow users to switch between touch strip modes. 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. This is not possible on Plasma Wayland: https://bugs.kde.org/show_bug.cgi?id=477787
