Hi, Don't know if this is a bug or just something to do with the resolution scaling that I'm not understanding. However, when I create a room with a size and viewport of 1280x720 and turn on full screen (1366x768) through window_set_fullscreen(true) then I find that the GUI layer is offset by 1 pixel. So if I draw in the draw_gui event, coordinates 0,0 are at 1,0 in the normal draw event. Is this a bug or am I misunderstanding how this should be working? Thanks.
