Running on macOS Sierra 10.12.2
When I run on my macbook air with the above parameters - no issues.
When I run on my lab’s macbook pro I have a bug. My fixation crosshairs come up while stimuli are still on the screen. This second computer is running OS X El Capitan 10.11.5 and PsychoPy v1.84.2.
Any thoughts why there would be a bug on one machine when it works on the other if they are running the same version of PsychoPy? Could it have anything to do with the different OS?
