I'm at a loss and haven't found anything that could help me with this. So for some reason whenever I start Total War Warhammer 3 (Steam Linux Runtime) a chromium process starts which seems to play a trailer or intro video from the way it sounds (it's a headless chromium as far as I can tell, so I don't see any window). The worst is that I can kill the chromium instance but it will just restart. The same happens if I let it run through, at some point it will just restart.

The only way to cope with this at the moment is for me to mute chromium in the Gnome sound settings. However, this mutes every chromium instance which isn't ideal.

No other Steam game (or game in general) is doing this.

Some info about my system: Endeavour OS with GNOME Desktop AMD Ryzen 3700X Nvidia 3070 with proprietary drivers
