The game will not render on Pop!_OS if window tiling is enabled. The game starts and grabs the mouse and keyboard, but the game window is not rendered.
I tried adding a Floating Window Exception for "steam_app_2354600" but that still did not work, I had to completely disable window tiling beforing launching the game.
Aside from the hour or so of troubleshooting to figure this out, the game runs perfectly without any additonal tweaks or configuration.
Nothing to report! Worked absolutely perfectly with no extra effort; even automatically set resolution just fine
Works out of the box with defaults!
Performance has improved in later patches. There's still FPS-drops, but more to 30-40 rather than 5-10 fps like it did previously.
Works out of the box with some minor slowdown at times
Some small text relating to instructions, but still legible
Some slow down when large numbers of enemies but not game breaking
Severe FPS drops with a lot of enemies on screen
