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
Spectacle rectangular region and active window screenshots don't work on setups with multiple screens: https://bugs.kde.org/show_bug.cgi?id=432260
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://bugs.kde.org/show_bug.cgi?id=433269
Some context menus appear in the wrong location as separate windows with titlebars: https://bugs.kde.org/show_bug.cgi?id=417378
Visual glitch behind integrated terminals (Dolphin, Kate, etc): https://bugs.kde.org/show_bug.cgi?id=432242

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

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.
