--- Comment #8 from Stefan Dösinger stefan@codeweavers.com --- The bug looks like some depth buffer issue.
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.
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.
