Additional Info

I have read reports of users otherwise getting the game running in wine/proton with a workaround, but i've been able to get it right as-of-yet

Workarounds suggest installing dotnet4.7.2 and gdiplus via winetricks - and modifying an erroneous png file

Start with the linked steam-1154840.log and the reproduction steps: launch a new game after the menu loads and observe the desktop drop while audio continues. Compare this with the listed Proton 5.13-2 environment and the documented dotnet4.7.2/gdiplus workaround. Done means the game remains visible and playable, with the compatibility cause documented.
