The only one of these that’s still a serious problem is the fullscreen on non-retina displays issue. However, I don’t know if people using newer versions of MacOS have encountered this again. Mostly, I was hoping to just have a record of the nature of the problem since it seems to recur periodically over MacOS updates and changes to PsychoPy’s display system
