Plasma/Wayland Known Significant Issues

This page tracks the Wayland showstoppers throughout the stack.

KWin/compositing/window management

When the compositor crashes, all apps crash too: https://bugreports.qt.io/browse/QTBUG-85631
No Wayland protocol for cross-app window activation/focus, so windows don't get brought forward when activated by another app: https://bugs.kde.org/show_bug.cgi?id=424795 https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/50
No Wayland protocol for app launch feedback, so there is no feedback on the cursor or Task Manager when an app is launched: https://bugs.kde.org/show_bug.cgi?id=402903 https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/50
Secondary screen doesn't come back on after disconnecting and reconnecting: https://bugs.kde.org/show_bug.cgi?id=434683
"Pin/keep open" functionality for Plasma applets does not work: https://bugs.kde.org/show_bug.cgi?id=400317
Very blurry fractional scaling for native Wayland windows due to using a downsampled 2x or 3x pixmap: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/34
Some menus appear in the wrong location as separate windows with titlebars:
- Context menus: https://bugs.kde.org/show_bug.cgi?id=417378
- In-titlebar app menu: https://bugs.kde.org/show_bug.cgi?id=430662
Visual glitch behind integrated terminals (Dolphin, Kate, etc): https://bugs.kde.org/show_bug.cgi?id=432242
GTK CSD apps don't display any window shadows: https://bugs.kde.org/show_bug.cgi?id=433977

XKB options sometimes don't work: https://bugs.kde.org/show_bug.cgi?id=433265
Touchpad Gestures:
- They are not configurable: https://bugs.kde.org/show_bug.cgi?id=402857
- They are very boolean, they don't show any feedback until they're executed.
Can't type accented characters in native Wayland Qt apps: https://bugs.kde.org/show_bug.cgi?id=411729 / https://bugreports.qt.io/browse/QTBUG-87088

Session restoring does not include Wayland native windows. Our sessions management recover engine is based on the 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 their wiki an own implementation for some time.
No activities. KWin now has minimal support for them, but the Task Manager doesn't know how to interact with them yet, and it's not properly persisted, so it doesn't survive session restarts. https://invent.kde.org/plasma/kwin/-/merge_requests/753
Context menus close immediately when the tooltip for thing that you right-clicked on closes itself: https://bugs.kde.org/show_bug.cgi?id=417939
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

Plasma crashes when dragging a file over the panel: https://bugs.kde.org/show_bug.cgi?id=398440
Can't abort drag-and-drop with the Esc key while dropped file is over Plasma panel or desktop : https://bugs.kde.org/show_bug.cgi?id=405267
