Hey guys, this really seems a ForceWare 169.xx series issue. These drivers series are problematic in OGL, even with the actual official WHQL release.
I never got this black-and-white-stripes issue, (my system is Vista 32 bit + 8800 GTX), but feanor got them with Vista 64 bit. See screenshot in
this closed thread.
If it is a 169.xx issue:
- Latest version, and official BTW, (.21 (XP) and .25 (vista)), seems to run fine BUT with -no_glsl. So official 3.6.9 build is not going to render fine.
- 163.75 should run fine.
- 169.xx has also a side effect with missing resolutions at least in Vista (1280 x 960 as example). I've posted a hack that at least works in my system. (No other guarantees).

Please confirm that this is (or not) your situation. Read this thread, it has all available info about the issue:
