The game is bugged on an ultrawide. If I set it as full screen, it kicks out to windowed mode every time anything happens going to/from games. 3440x1440 for sure doesn't work, I don't have a screen with a higher resolution to test but this is extremely annoying. This is an easily reproducible bug. I shouldn't have to upvote something like a reddit thread to get base functionality for an extremely common monitor resolution to behave normally.
