I'm having graphics issues with my freshly installed Ubuntu 20.04. I've added a picture to show you the graphic glitches happening randomly. There is no clear pattern. It occurs very shortly (in a fraction of second), so it was quite hard to capture that picture.
This question was already answered before, but the solution didn't work. The error came back.
