Description Josep Febrer 2021-11-24 23:43:44 UTC 
SUMMARY
***
After building KWin from the latest git master I found that when I activate the zoom effect on Wayland the screen freezes and the cursor disappears. I haven't found a way to restore it.
I have to go to a tty to restart the session. When the freeze happens I discovered that the keyboard is still responding because I can stop a window which is playing music with a keyboard shortcut but even if I exit the session with a keyboard shortcut the screen remains friezed as nothing happened.
Under X11 I can use the zoom effect as usual without any issue.
***


STEPS TO REPRODUCE
1. Turn on the zoom effect on system settings.
2. Use the zoom effect with a keyboard shortcut.

OBSERVED RESULT

The screen freezes completely and I have to go a tty to be able to restart the desktop session.

EXPECTED RESULT

The screen should be zoomed.
