URL of experiment: https://pavlovia.org/mkallmayer/mouse_test (minimal working example)
Description of the problem: Not my MacBook so I don’t know the exact model, but I was told it’s a new one.
I am trying to track the mouse position (using getPos()) and check it each frame. On all Windows/Linux machines I’ve tried to run it on it has worked so far, however on this machine it doesn’t. A constant mouse position around (-1.4, 0.5) is printed out to the JS console, no matter how much you move the mouse around.
Could this be retina display related?
