Symptoms

Game doesn't run under proton.

Reproduction

• Configure the game to run under proton. I set mine to Proton 6.3-6 (also tried with Experimental)
• Launch the game.
• In VR: A small window with black content appears, stays a few dozen seconds, then disappears.
• In pancake mode: the screen turns black, stays a few dozen seconds, then exits to the desktop.

Note: the game has a native version. However running it in proton might be advantageous under a number of scenarios. One of these is using the game in VR, since the linux build does not have VR capabilities. Also, it's a free game, so testing it is very easy.

My suspicions of where the problems might be:
52472.762:0140:0170:fixme:msctf:ThreadMgr_ActivateEx Unimplemented flags 0x4
or
52472.762:0140:0144:err:ole:CoMarshalInterface Failed to marshal the interface {ea1ea136-19df-11d7-a6d2-00065b84435c}, hr 0x80004002

Start with the linked steam-1256380.log and reproduce the launch failure using Proton 6.3-6 or Experimental in VR and pancake mode. Compare the reported msctf and OLE messages with the observed black window and exit; done means FPS Infinite launches successfully in the requested mode.
