Eye tracker ROIs color problem

Hello everyone,

I am running an experiment with an eye tracker connected to psychopy. We made the experiment with the version 1.2 and it works fine but with the new version 3.0 we encounter a problem.
The ROIs of the eye tracking ( two rectangular areas right and left) turn red automatically for no apparent reason. Any ideas why changing version would have this effect?
Any feedback would be appreciated. Thank you very much.

My best regards,
