You need to update your video card driver, because the driver has a bug.
If you can't find an updated driver from the GPU maker's web site, then you could also try disabling OpenGL drawing in preferences.
I've actually tried updating my driver before, because the screen resolution wasn't working right. I'm not sure if that worked, but I downloaded ATI display driver software and I got my screen resolution to work right. I just tried updating my driver through the device manager and windows says my driver software is up to date.
I disabled OpenGL drawing and it works fine now. However, won't this be a performance decrease?
