yes, ctrl+f works fine. but that's after my resolution has already snapped back. and there doesn't appear to be any way to change resolution after the program has launched
just tried 1280x720 fullscreen and that snapped back to a 3:4 ratio, too. it has no problem launching into fullscreen. the splash screen comes up as intended 16:9 resolution, then it snaps to a random 3:4 resolution--still in fullscreen.
