Unity engine backtrace on crash

Disco Elysium is a relatively new game using Unity 2019.1.?? engine. 

Using wine 5.0-rc3, and launching from Steam, with Wine set to "Windows 7"
compatibility, it is possible to get into the character creation part,
pre-game. 

Starting the game itself with any character causes an almost immediate crash,
presumably as the 3d engine is initialised for the game proper. (This is caught
by the Unity bug tracker.)

I'll attach full logs as requested, but here I will note that the wine output
displays:

018a:err:d3d:wined3d_debug_callback 0x81596a0: "GL_INVALID_OPERATION error
generated. Transform feedback must be enabled and not paused.".
018a:err:d3d:wined3d_debug_callback 0x81596a0: "GL_INVALID_OPERATION error
generated. Buffer is mapped.".

twice just before the crash is caught. 

The Unity backtrace, attached, suggests that the crash happens in the nvidia
libraries, but it isn't clear to me that this is the fault of the nvidia
drivers themselves.
