--- Comment #10 from Stefan Dösinger stefan@codeweavers.com --- (In reply to Berillions from comment #9)
I tried this : 1- I launch the game with the Intel card WITH "VideoPciVendorID" and "VideoPciDeviceID" from Nvidia and i have this bug. 2- I launch the game with the Nvidia card WITH "VideoPciVendorID" and "VideoPciDeviceID" from Intel and there isn't this issue.
So, this test confirm that it's an upstream bug from Nvidia/Nouveau ?
No, this shows that the game behaves differently if it finds an Nvidia card and does something that Wine and/or the driver does not support. I suspect it tries to use nvapi.dll's advanced StretchRect call.
If you have a Windows installation on the same machine you can confirm this theory by renaming C:\Windows\system32\nvapi.dll and C:\windows\syswow64\nvapi.dll to some other name and start the game. If my theory is correct you should see the same bug as you do on Wine. (That assumes you're using the Nvidia card on Windows.)
