Plasma/Wayland Known Significant Issues: Difference between revisions

Revision as of 17:14, 20 September 2021

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 —according to their wiki— an own implementation for some time.

KWin/compositing/window management

User Switching doesn't work: https://bugs.kde.org/show_bug.cgi?id=439873
When the compositor crashes, all apps die too: https://bugs.kde.org/show_bug.cgi?id=437709
Changes made to cursor theme/size do not take effect in Qt and XWayland software until the session is restarted (takes effect immediately in GTK software though): https://bugs.kde.org/show_bug.cgi?id=420859
Windows that were closed when maximized will open in the maximized position, but not the maximized state: https://bugs.kde.org/show_bug.cgi?id=437089
Automatically chosen scale factor on high DPI screens does not effect until manually applied: https://bugs.kde.org/show_bug.cgi?id=433460

Plasma

Saving and restoring activities does not work
Plasma crashes when monitor goes into standby: https://bugs.kde.org/show_bug.cgi?id=420160

System Settings

Font Management KCM doesn't work/isn't visible: https://bugs.kde.org/show_bug.cgi?id=439375

Drag and Drop issues

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

Qt/Wayland/other upstream

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
No color management: https://bugs.kde.org/show_bug.cgi?id=439135 / https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14
KDE app windows don't get brought forward when activated by another KDE app: https://codereview.qt-project.org/c/qt/qtwayland/+/321246 (in review: ; support will come sometime for Qt 6)
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
Context menus mis-positioned in multi-screen setups: https://bugreports.qt.io/browse/QTBUG-85297
Some context menus are misaligned in Qt apps: https://bugreports.qt.io/browse/QTBUG-68636

-* Windows don't get brought forward when activated by another app. The Wayland activation protocol that we proposed has been merged, and now every toolkit needs to add support for it.
-** Qt: In review: https://codereview.qt-project.org/c/qt/qtwayland/+/321246; support will come sometime for Qt 6
