Every time I boot the game and get to the main menu there's a graphic error which displays as one of those old rainbow TV "no signal" screens. I can still access behind it -- I randomly clicked and presumably hit New Game and the game plays as normal. Then, whenever something happens (animation?) the glitch returns. This is not a hardware deficiency on my end -- my machine clears all benchmarks -- however I am using Steam Linux. (Yes I've tried repair, reinstalling, etc.) Any troubleshooting help? Thanks in advance
