It's possible that this is a driver bug on both Nvidia and Noveau. It's also possible that the Nvidia card has some features that the Intel card does not have that makes the game use a different codepath. I'd suggest to check the game settings, try to set them to the minimum and see if the bug goes away; If it does, raise them until you find the setting that brings the bug up. See if that setting is available at all on Intel.
I tried to change all graphic settings in-game. There are no difference. Still this issue even if i set them to minimum.
It's also possible that the game expects nvapi.dll to be available when it finds an Nvidia card. You can try to set VideoPciVendorID and VideoPciDeviceID to fake an Intel card when you're using the Nvidia one or vice versa and see what effect this has on the bug.
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 ?
