Description Naxdy 2023-08-26 09:42:37 UTC 
SUMMARY
When in Wayland and XWayland crashes or is killed, newly started X windows are offset slightly to the top. This results in the top UI elements being hidden behind the title bar, and an awkward empty space appearing at the bottom between the shadow and the window contents, and global menu no longer works.

Note that this issue can be somewhat worked around by setting the window to borderless.


STEPS TO REPRODUCE
1. Log in to Plasma Wayland 
2. Start at least 1 X window
3. Brutally murder XWayland by killing its process
4. Open another X window

OBSERVED RESULT
The newly opened X window contents are offset slightly to the top, and global menu is no longer functional for that window

EXPECTED RESULT
The window contents appear the same as before, and global menu is functional

The offset issue should be fixed in 6.0.0 (it was caused by using outdated cursor atoms). The global menu is something different, if it's still an issue please file a new bug report for plasmashell.
