wine-1.1.32-260-gf222a16 OpenGL renderer string: GeForce 8800 GTS/PCI/SSE2 OpenGL version string: 3.2.0 NVIDIA 190.29
Downloaded the demo again, the issue is still present, same as comment 72 still.
FWIW, the issue in http://bugs2.winehq.org/attachment.cgi?id=14612 looks like depth buffer precision differences between the onscreen and offscreen depth buffer. I think this might only be a problem for GF8 and later cards.
