SUMMARY
With three monitors connected, when I maximize Firefox on the leftmost display, it freezes Plasmashell. If I interact with Plasma, such as clicking an application to open it, nothing happens, but when I minimize Firefox, those applications then open.

STEPS TO REPRODUCE
1. Connect three monitors.
2. Maximize Firefox on the left monitor.

OBSERVED RESULT
Plasmashell freezes

EXPECTED RESULT
Plasmashell works as expected

Can't test this since I have not enough monitors, but just FYI, It says video is not available anymore.

It is actually *plasmashell* specifically that freezes, or is it something else, like maybe KWin?

Is Firefox running in XWayland mode, or native Wayland mode?

Does this happen on X11 too, or only on Wayland?

Does it happen in a new clean user account with the same screen setup?

This suddenly stopped happening, not sure which package upgrade fixed it.
