Symptoms

At the same point at quest cutscene i got black (mostly) artifacts and my game crashes. Quest "The Defense of Seliana", it's the most obvious crash that i can reproduce. There was more in game before but i avoided it. I tried DX11, DX12, low graphics settings, multiple proton vesions, WINEDLLOVERRIDES="dxgi=n" %command%, nothing works, crash every time. Here is a screenshot:

Reproduction

Launch the quest "The Defense of Seliana" and watch 30 seconds of cutscene
