Plasma/Wayland Known Significant Issues

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

Session management

• User switching doesn't work: https://bugs.kde.org/show_bug.cgi?id=435389
• 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.

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

• Some menus appear in the wrong location as separate windows with titlebars:
