Honestly, I have no faen clue, but that’s an assumption, I wouldn’t make without knowing.
May be the easiest would be to put your monitor resolution to non-retina (just a fixed default of say HD). As said, I will attempt some tests on my rig (since I can have retina - the new one *4) is set by default on both MAC and WIN. Running the tests in both environment at different resolution will take a bit of time though! I’ll let you(rs) know when I get a chance to test this.
