Update: I've continued testing this bug in recent versions of WINE (1.7.2, 1.7.3, 1.7.4, 1.7.5, 1.7.6), and the bug is still continuing to appear.
The only fix so far has been to use WINE 1.7.1 with the CSMT patches from Stefan Dösinger.
I can confirm this result. Bug is present on nVidia hardware in recent stock versions of Wine, and bug is absent with 1.7.1-CSMT and 1.7.4-CSMT.
