Plasma/Wayland Known Significant Issues: Difference between revisions

This page tracks the Wayland showstoppers throughout the stack.

No cross-app window activation/focus protocol. As a result, 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 vertical/horizontal maximize of Wayland native clients. KWin uses NetWM modes internally to do this. Works with Xwayland clients. Would also work for Wayland clients, just the state cannot be exported to Wayland (c.f. Quick tiling).
XWayland windows are upscaled and look blurry and ugly in HiDPI mode: https://bugs.kde.org/show_bug.cgi?id=389191
Cursor lags under high CPU load: https://bugs.kde.org/show_bug.cgi?id=421131
"Pin/keep open" functionality for Plasma applets does not work: https://bugs.kde.org/show_bug.cgi?id=400317

No configurable mouse gestures; X has the ability to accept fake input events to allow programs such as Easystroke. With the new security model of Wayland, such a program would need to be part of the compositor.
No XModmap; we lack a functionality like XModmap to remap keys.
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.
Session sometimes crashes when changing Global Themes: https://bugs.kde.org/show_bug.cgi?id=422424

Session crashes when hovering over task manager after dragging an entry in task manager to another virtual desktop: https://bugs.kde.org/show_bug.cgi?id=418683
plasmashell crashes when dragging a file from Dolphin over a panel: https://bugs.kde.org/show_bug.cgi?id=398440
Cursor sometimes erroneously displays "no drag possible" icon even when it is possible: https://bugs.kde.org/show_bug.cgi?id=383794
Can't abort drag-and-drop with the Esc key: https://bugs.kde.org/show_bug.cgi?id=405267

-== Remote control support incomplete ==
-* Our screencasting API handles remote video streaming, but there is no API for remote input, so things like TeamViewer have no way to work (and would need to be ported to use those APIs once they exist).
