Strange graphics bugs.

[Pehmu]

I was able to fix this problem by changing my resolution to the monitor's native 1680x1050 (strangely, it also worked in 1024x768 but produced similar errors in 800x600 and the packaged widescreen modes)

Yeah, I've been using my monitor's native (1440x900) all this time, but it makes no difference. =/

I also tried 177.93 beta drivers and 177.83 drivers toyota582 mentioned in his last message. So far none of these have helped.
