Symptoms
I have an issue with alt-tab. After alt-tabbing I can't return to the game. It shows me only black screen with small icon in the top left corner:

I have this issue with both Proton 3.16-4 and 4.2-4. Virtual desktop doesn't work for me (mouse stucks on left side of the screen).
I have two fullHD monitors.
I also have this issue with Cuphead (#796).
