Okay so I tried setting project fullscreen to "OFF" and creating a list of all resolutions. Just as a test, I set the resolution to 640 x 480 and set the canvas size to 640 x 480 and requested fullscreen - centered.
Everything looked as if it was shifted to the left and down a bit. What am I doing wrong?
EDIT: I think I'm thinking I'm changing the window size when that's not the case...There's no way to change the project window size, is there?
