A few seconds after opening dimension, the user interface turns into a fractal animation show. When I go with the mouse over the distortion, everything looks normal, but secs later, the show goes on again. In the dark an ligth theme. I have similar effects, in Premiere Pro CC and Aftereffects CC, but only in the tutorials thumbs and not animated and not over the complete surface. I mean, this starts with the new Geforce.
System: WIN 10, i7 2600K, 32 GB Ram, Geforce RTX 2060 super (studio driver)

This bug "ticket" could close. I found out, that the problem is a new function in the nvidia display driver. The new function "Image Sharpening" courses the bugs into the program surface. If you turn off the sharpening, everything works fine. :)
