Comment 2 for bug 1789713

Thanks for the reply.

I will try and come back if it's not solved.
Anyways I'm not talking about screen tearing,... the screen turns completely black and comes back for a few times... totally randomly.

After disabling the desktop effects I didn't noticed it happen for some time, until today.
So disabling the desktop effects didn't solve the issue. I enabled the option back.

I did have selected a refresh rate of 120Hz, which I changed to 59.9Hz.
If this doesn't fix the issue I will report the issue in the support forum.
