iMac Pro driver resolution problem

Hello everybody,


I'm italian and i don't speak english, i help with google. I'll try to write simple.

I have no problem with the drivers until October 2020. 

All drivers released after the month of October 2020, give me a strange problem.

When the computer goes into standby (sleep) and is reactivated, the resolution changes and the computer becomes unusable.

I am forced to restart it.

Is anyone aware of this problem?

I have an iMac Pro 2017

Yours sincerely
