Plasma/Wayland Known Significant Issues

This page tracks the Wayland showstoppers throughout the stack. This is part of KDE's Wayland goal.

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, or launch feedback: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/50
- Windows don't get brought forward when activated by another app: https://bugs.kde.org/show_bug.cgi?id=424795
- No feedback on the Task Manager when an app is launched: https://bugs.kde.org/show_bug.cgi?id=402903
- No feedback on the cursor when an app is launched: https://bugs.kde.org/show_bug.cgi?id=405624
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

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.
Saving and restoring activities does not work
