Description Adrian Wannenmacher 2021-05-02 19:17:12 UTC

SUMMARY
If you are dragging a window with the mouse, and simultaneously move it to a different virtual desktop using a shortcut, the mouse becomes unusable and you cannot focus any other window.


STEPS TO REPRODUCE
1. Add a shortcut for "Move window to next virtual desktop".
2. Drag a window with the mouse.
3. Simultaneously use that shortcut.

OBSERVED RESULT
It is no longer possible to use the mouse, the cursor remains the "move window" cursor. It is also no longer possible to focus any other window. The window itself also no longer responds.


EXPECTED RESULT
The desktop should remain usable. This is the case if doing the same but using the "Change to next virtual desktop" shortcut.
