SUMMARY
In a plasma-wayland session, the mouse cursor no longer changes shapes in XWayland windows.


STEPS TO REPRODUCE
1. Start a plasma-wayland session.
2. Run WAYLAND_DISPLAY="" gtk3-demo --run=cursors
3. Click on the buttons.

OBSERVED RESULT
The cursor shape does not change at all. It only changes after switching window and back using Alt-Tab, and then it stays whatever shape it is, again.

EXPECTED RESULT
The cursor should change its shape after clicking those buttons.
