Hey folks. I'm having problems with Dungeons of Dredmor since updating from Windows 8 to 8.1. When I load up the game, the main menu doesn't fit properly on the screen, no matter what resolution I use, and then the mouse cursor jerks around, disappearing and reappearing in a random place. It's so bad that I can't even select 'quit' on the menu, and instead have to alt+tab out and close it with Task Manager. Extensive Googling hasn't brought me any way to resolve this so anything you can tell me would be greatly appreciated. (I've tried verifying the integrity of my Steam cache and also uninstalling/reinstalling, to no avail).
