Plasma/Wayland Known Significant Issues: Difference between revisions

Revision as of 04:35, 1 May 2021

This page tracks the Wayland showstoppers throughout the stack. Showstoppers are major bugs, crashes, or missing features affecting the Wayland session but not the X11 session. This is part of KDE's Wayland goal.

Clipboard management

Plasma fails to paste text copied from XWayland apps: https://bugs.kde.org/show_bug.cgi?id=424754
Text copied from a GTK app makes it into Klipper, but cannot be pasted after the GTK app quits: https://bugs.kde.org/show_bug.cgi?id=424649
Can't copy text from notifications: https://bugs.kde.org/show_bug.cgi?id=434675 (very annoying for text messages with a long code you need to enter into a website for 2-factor authentication purposes)

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

Session doesn't start with NVIDIA GPU and proprietary drivers: https://bugs.kde.org/show_bug.cgi?id=435673
When the compositor crashes, all apps crash too: https://bugreports.qt.io/browse/QTBUG-85631
Window activation / launch feedback:
- Windows don't get brought forward when activated by another app: https://bugs.kde.org/show_bug.cgi?id=424795
- No feedback on the Task Manager when an app is launched: https://bugs.kde.org/show_bug.cgi?id=402903
- No feedback on the cursor when an app is launched: https://bugs.kde.org/show_bug.cgi?id=405624
Secondary screen doesn't come back on after disconnecting and reconnecting: https://bugs.kde.org/show_bug.cgi?id=434683
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
Titlebar button app menu appears as a separate window: https://bugs.kde.org/show_bug.cgi?id=430662

Plasma

Plasma randomly crashes in QWaylandClientExtensionPrivate::handleRegistryGlobal() when changing settings in System Settings: https://bugs.kde.org/show_bug.cgi?id=414834
plasma-browser-integration-host crashes in a loop when Firefox asks to be the default browser: https://bugs.kde.org/show_bug.cgi?id=435811
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 / https://bugreports.qt.io/browse/QTBUG-83972
Cannot unlock session after external screen turns off: https://bugs.kde.org/show_bug.cgi?id=428706
Saving and restoring activities does not work (everything else does, though).
Task Manager thumbnails sometimes don't work: https://bugs.kde.org/show_bug.cgi?id=427826

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
