Large black squares in game

[SirEyck-1373]

No I didn’t update the graphics drivers but there are no newer drivers available
Others with dedicated cards are having the same problems:

Black box textures/animations in some acts

Large black textures flashing really fast. Started act 2 where the boundaries of the map are. In act 4 much more severe, usually where dead monster are on the ground. It blinks a lot and makes impossible to see what is happening.
