Description Antti Savolainen 2024-04-22 02:45:54 UTC 
SUMMARY
If I open Serious Sam 3 on a secondary monitor while using Polonium tiling script, it will cause Kwin to freeze completely. Sometimes it recovers after a few seconds and renders the game and Steam invisible and sometimes it will never recover. If I do the main monitor, nothing out of the ordinary happens

STEPS TO REPRODUCE
1. Install and activate Polonium
2. Move Steam to a secondary monitor
3. Make sure Serious Sam 3 is set to launch natively and not through Proton
4. Open Serious Sam 3 in Steam

OBSERVED RESULT
Kwin freezes completely

EXPECTED RESULT
No freeze should happen

Does this happen without the Polonium tiling script? Is this on wayland or x11?
Comment 2 Antti Savolainen 2024-04-22 04:04:42 UTC 
I'm using wayland and it does not happen without Polonium. I recorded a recreation of what I would do to trigger the freeze but without Polonium so that there's some repro steps in video form: https://youtu.be/HadTzhOa00U

Please report this to the developers of polonium as this seems like an issue with polonium.
