Ancheng: I don't test it on Linux. By the way, in Ubuntu18.04 Wine environment,
I often encounter some errors in the App installation process, or some errors
not related with D3D when run the App.

Ancheng: In my environtment the OpenGL driver is from NVIDIA, seems not
implement the wine-specific extension?

Ancheng: I try to initialize cs_multithreaded with WINED3D_CSMT_SERIALIZE or 0,
it still fails, the App D3D window is black.

Ancheng: It is from attaching the debugger and from breaking manually.
