The only thing I can guess is that you're running in 8-bit (256-color)
mode and your graphics card is being too clever and dithering even
when it's not supposed.  Running in 32-bit depth is the best solution
to this problem, but I'd also consider that graphics card and/or
driver to be suspect and one or both probably should be upgraded.
