This page tracks the Wayland showstoppers throughout the stack. Showstoppers are major bugs, or missing features affecting the Wayland session but not the X11 session. This is part of KDE's Wayland goal.
Login/Session management
- Session restoring does not include Wayland native windows: https://bugs.kde.org/show_bug.cgi?id=436318. 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 had their own implementation for some time.
- Windows that *are* session-restored go on the wrong virtual desktops: https://bugs.kde.org/show_bug.cgi?id=421870
- Session-ending actions don't work after kwin_wayland had to restart for any reason: https://bugs.kde.org/show_bug.cgi?id=449948
KWin/compositing/window management
- When the compositor crashes or restarts, all apps are killed
- On Wayland, the compositor doesn't expose the minimized state. Some application and library code currently does things based on that state (usually to show their window again if needed, typically by calling QWidget::isMinimized()). Example: KNotifications' KStatusNotifierItem in KStatusNotifierItemPrivate::checkVisibility(...), invoked e.g. on clicking the item, uses the info to decide client-side whether to request showing the window again (or hide it)
- In multi-monitor setups with at least one scaled display, Plasma context menus have items which are invisible until hovered: https://bugs.kde.org/show_bug.cgi?id=432264
- When using scaling, logging into Wayland session after X11 session resets scale to 1: https://bugs.kde.org/show_bug.cgi?id=433460
Plasma
- Saving and restoring activities does not work
- Monitor connector names are different across X11 and Wayland, so logging into a Wayland session from X11 breaks multimonitor layout and Plasma configs: https://bugs.kde.org/show_bug.cgi?id=385135
- XEmbedSNIProxy window eats input in top-left pixel of the screen: https://bugs.kde.org/show_bug.cgi?id=433079
- Some apps don't appear in Task Manager: https://bugs.kde.org/show_bug.cgi?id=444325
- Doesn't respect cursor theme at all: https://bugs.kde.org/show_bug.cgi?id=454616
- Phantom non-interactive desktop icons sometimes appear: https://bugs.kde.org/show_bug.cgi?id=453937
System Settings
- Gamma KCM doesn't work/isn't visible: : https://bugs.kde.org/show_bug.cgi?id=439135 & https://invent.kde.org/plasma/kwin/-/issues/11
- Graphic tablet KCM is very barebones compared to X11 version: https://bugs.kde.org/show_bug.cgi?id=433045
Blocked on required upstream changes
- When using a fractional scale factor, native Wayland apps are slightly blurry: https://bugs.kde.org/show_bug.cgi?id=446674; requires https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/34
- No color management: https://bugs.kde.org/show_bug.cgi?id=439135; requires https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14
- KDE app windows don't get brought forward when activated by another KDE app: requires Qt6; support was added in https://codereview.qt-project.org/c/qt/qtwayland/+/321246
- KDE app windows activated by Electron apps don't get brought forward due to lack of support for the Activation protocol in the toolkit: https://github.com/electron/electron/issues/30912
- Picture-in-Picture windows from web browsers do not stay on top: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/44
- When a notification times out, it closes any context menus that are open and then blocks the next two right-clicks: https://bugs.kde.org/show_bug.cgi?id=427542; requires https://codereview.qt-project.org/c/qt/qtwayland/+/347783
- Installed Chrome apps do not show up as a unique app but instead assume the Chrome icon, in Icon-Only Task Manager: https://bugs.kde.org/show_bug.cgi?id=358277
- Wrong positioning of context menu in multiple screens: https://bugs.kde.org/show_bug.cgi?id=436016; requires https://bugreports.qt.io/browse/QTBUG-85297
- Impossible to pick a screen color: https://bugs.kde.org/show_bug.cgi?id=415927; requires https://bugreports.qt.io/browse/QTBUG-81538
- QDockWidget does not visually move when moving and is not re-dockable when detached https://bugreports.qt.io/browse/QTBUG-87332
