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
• "Pin/keep open" functionality for Plasma applets does not work: https://bugs.kde.org/show_bug.cgi?id=400317
• XWayland windows are upscaled from a 1x pixmap and look blurry and ugly in HiDPI mode: https://bugs.kde.org/show_bug.cgi?id=389191 and https://bugs.kde.org/show_bug.cgi?id=433115
• 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

Input

• XKB options don't work: https://bugs.kde.org/show_bug.cgi?id=433265
• Touchpad Gestures:
  • They are not configurable
  • 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.
• No activities. KWin now has minimal support for them: https://invent.kde.org/plasma/kwin/-/merge_requests/753
• Session sometimes crashes when changing Global Themes: https://bugs.kde.org/show_bug.cgi?id=422424
• Plasma sometimes crashes when changing Global Themes: https://bugs.kde.org/show_bug.cgi?id=414834 https://invent.kde.org/plasma/kwayland-server/-/merge_requests/156
• 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)

Drag and Drop issues

• Plasma crashes when dragging a file over the panel: https://bugs.kde.org/show_bug.cgi?id=398440
• Cursor sometimes erroneously displays "no drag possible" icon even when it is possible: https://bugs.kde.org/show_bug.cgi?id=383794
• 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
