I've seen a video placeholder (which means a video codec(s) related meta-issue) on the start of the game (right before the menu appears), current stable Proton 6.3-3.
@aeikum The crash on exit is indeed fixed with 3.16-7. I haven't done a fully play test yet, but if nothing new breaks, I would consider this whitelist ready.
With Proton Version 3.16-6 and by that FAudio, the games audio works out of the box. The game is then fully playable. However, it still crashes on exit and forces me to kill the defunct process. Sysinfo: https://gist.git...
