That's weird. I unfortunately couldn't recreate the problem. Might look further into it if it's happening to more people.
Well, But I think that it could avoid strange things like this by adding a options menu that can fit the resolution (example, switch from 1080x720 to 1920x1080) or a windowed version.
Yeah, making it the game launch in windowed mode might be the way to go. Thanks for your feedback; I'll probably change it in the near future.
