Symptoms

Launching the game loads into a black screen. There is audio and the game accepts inputs but has no video output. If launched via protontricks outside of steam using the game's appid for the specifically chosen proton version the game runs fine minus the ability to use launch commands. They just dont work.

Reproduction

With empty launch commands make sure you're running one of the proton versions listed, and launch the game. It may take a few moments before the window shows up. Sometimes it doesn't open and crashes instead.
