Psychopy experiment run - corrupted display/ blurry | printscreen shows correct image

Hello,

I’m experiencing a tough issue. I really hope that someone can help.

OS (Win10):
PsychoPy version (2021.2.3):
**Standard Standalone? (y)
What are you trying to achieve?:

When running an experiment at full screen mode. The display buffer seems to be overrun. The image being displayed on my screen seems to be corrupted, i.e. I can see the image to be displayed but there are blurred dancing pixels on the entire screen.
Important info: when pressing alt+tab then the problem disappeared, when I press on the image (as if bringing psychopy to the front, the problem returns. Now I wanted to print the screen and show an example but printscreen get the correct image - no noise on top.
To me it seems as a bug in psychopy.

I’m using a brand new computer, on my prev computer, I didnt experience this.

Thank you.

It sounds like you have incorrect monitor settings in PsychoPy (which are for your previous computer ).
