Symptoms

The game starts and runs fine, the widespread fog issue is not present out of the box either, the Hardware.ini file seems to have the fix for it pre applied. However, I do have encountered some other bugs:

Player shadow glitch: The shadow effect under the player starts to behave strangely after jumping, rolling or suddenly changing direction. Two rectangles start to appear gradually and they follow the player's movement. The glitch disappears though, after alt-tabbing out of the game, then back to it. Then it appears again, after jumping around. I've tried all the different Proton versions, and also changing the in-game graphic options. Only turning off all shadow effects fixes it, but that cuts back on the experience. It might not be a Proton specific issue, but I haven't been able to find this bug mentioned anywhere, not on PCGamingWiki, ProtonDB or WineHQ.

No Steam Overlay: Even though Steam Overlay is enabled globally and also specifically for the game, it doesn't work. This means I can't see the current FPS value, but more importantly, I'm not able to use a controller with the game, that I set up with Big Picture Mode's controller options. In BPM, there's also a warning for the game that the overlay is disabled, and controller options won't work.

Reproduction

Just run the game normally. Any help for fixing these issues on my own would be appreciated.

Reproduce Steam AppID 13600 under Proton using the attached steam-13600.log, the system information report, and the reported Hardware.ini setting. Trace the shadow and Steam Overlay/controller failures from the compatibility behavior described; done means the issues are fixed or their external cause is documented.
