SUMMARY

Having multiple screens with different scaling factors in the plasma wayland
session makes it impossible to exit fullscreen video playback. The screen that
played back the video becomes unusable, the second screen works fine. Graphical
glitches can be observed on the primary screen when trying to exit the full
screen playback.


STEPS TO REPRODUCE
1. Set different scaling factors on two monitors.
2. Start playing back video in full screen mode (tried firefox (Youtube,
Netflix) as well as VLC (local file).
3. Try exiting the playback.

OBSERVED RESULT

The screen becomes unresponsive and shows graphical artifacts.

EXPECTED RESULT

The video playback can be exited normally.
