I simply choose 1280x720 not full screen but for some reason... if you were to change it to 1600x900 your mouse detection gets displaced. As for a "monitor" I am currently stuck using my tv until I get a new one. But yeah, changing resolutions causes the mouse to not be detected correctly. And I just found another bug. If you were to change the resolution from 1280x720 to 1920x1080 your mouse doesn't register anymore. You can still close the window but otherwise can't select the options or much of anything. Hope it gets soon, I may have screwed myself over by testing this out. Is there a way to change the resolutions via a hotkey of some sort?
