Someone else ran into that problem, though I have no idea what causes it.
There's a 2x resolution option in the options menu, you should be able to reach it pretty easily. When the main menu loads in, press down once, then press enter to get to the options menu. Then just press enter again.
Hope that helps!Edit: If you have a high DPI monitor there might be some display settings you can change to fix the issue.Edit 2: Nevermind, found the issue!
