Ancheng: is there any quick workaround for me to avoid the above error?

Ancheng: My environment: Windows VM + NVIDIA T4 GPU(Passthrough mode), replace
d3d9.dll, d3d11.dll, dxgi.dll and wined3d.dll with Wine. In this case when run
Revit, the GPU occupation is higher(5%-20%). In the original NVIDIA D3D dll
environment， d3d10warp.dll is loaded by Revit and also use GPU hardware to
render(GPU occupation is higher). So seems that Revit just uses WARP driver to
render in some cases, it also uses GPU HW to render. 

I attach a full log from openning Revit to the black screen bug, any
sugguestion is welcome, I can try your idea in my environment. Thanks a lot.
