Link to the most relevant existing thread you have found: "Attempting to measue frame rate of screen" stuck - #15 by TParsons
What specifically went wrong when you tried that?:
This worked perfectly fine a week ago. But experiment suddenly was stuck on the frame rate measurement for ages, so I unchecked that and set it to 60. Even thought it was some minor updates that I added to the experiment that caused it so I redownloaded the older builder files to check. That didn’t help as well - I now see a white rectangle with the python (not responding) no matter how many times I’ve restarted it… Doesn’t show any errors too just perpetually on monitor calibration
