We could not catch that. Is this occuring in the fullscreen mode or windowed mode?
I searched for the problem and I think it is because of the display scaling of your mac. I noticed from your screenshot that it is 3024 x 1952. It seems it does not match with the Windows scaling. It is the first time for us to encounter this kind of problem :( We will try to rebuild the game accordingly ^^ Btw we added another fullscreen button on the bottom right, could you check if it helped in any way?
