Can't reproduce with Proton 5.0-4, AMD GPU + Mesa drivers.
To prevent the game from auto-crashing, have to set emulate virtual desktop in the winecfg. Once this is set, have to enable Fullscreen in game. Can remove emulate virtual desktop setting afterward. Game works thereafter on current and older proton versions.
