Default [BUG REPORT] 3d rendering polygon glitches in COD4 with 180.35 and above

I get weird rendering glitches (extra polygons) when playing COD4 under wine if I use nvidia 180.35, 180.37, 180.41, or 185.13. See the attached jpg for an example, which is supposed to show a couple of cars. The first level is unplayable, as it renders the screen as three polygons in slightly different shades of gray.

The glitches only occur when I run it at the screen's native resolution (1680x1050), not in the next resolution down. It does it whether in full screen or in a window, with or without compiz running. It is consistent, and the GeForce 8600M GT nvidia card is running at normal temperatures (typically 57C-70C).

The graphics render fine with nvidia 180.29 and earlier using the same xorg.conf settings. So the regression first occurred in 180.35.

I've tried combinations of these drivers on Ubuntu 8.10 with both kernel 2.6.27-14-generic amd64 and 2.6.28-11; and Ubuntu 9.04, kernel 2.6.28-11 and the results are the same. I've tried different versions of wine (1.1.12 and the latest from git) and the results are the same.

The glitches seem to have improved slightly with 180.41. The attached cars image was generated with 180.41 - with 180.37 and 185.13 you can't even recognize that they are cars.

Any ideas?
