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

Input

• 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

Plasma

• 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.
• 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 / https://bugreports.qt.io/browse/QTBUG-83972
• 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
• Cannot unlock session after external screen turns off: https://bugs.kde.org/show_bug.cgi?id=428706
• Saving and restoring activities does not work (everything else does, though).

Drag and Drop issues

• 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
