Works fine for me on RTX 2060 Super in both Windowed and Fullscreen.

Yes, we were never able to reproduce any shenanigans, except for vertex buffer robustness behavior which was a thing, but has been fixed. Don't think this issue is valid anymore.
Nothing extracted yet.
Need to repro a black screen on 450.57 with GTX 1060 (unsure if Pascal specific, probably not) using standalone build.
