I have it too, even worse than the flickering, I do have complete black boxes, where only dropped items are visible. Can’t post pictures in here unfortunately, some areas are just unplayable for me.
Switching to older drivers does not work for me, D2R did not start at all with older drivers. But switching o legacy-view I will try. Since I am using a surface Pro, I was not expecting too much, it’s kind of sad anyway. D3 is running smoothly…
