I can't seem to apply a wallpaper in Windows 7 without a very strange behaviour: The wallpaper appears corrupted: Too much exposure in the picture -- and if I try another picture, then the new one and the previous one appear to be merged into one.
This doesn't happen most of the time when I apply a wallpaper through the "Window Blinds" application (and yes, the problem was present before I installed Window Blinds).
Anyway, this has got to be either:
A VERY strange setting accidentally enabled
Something wrong with my graphics card (but I have no other problems at all with the graphics card).
Does anybody know what could be going on?
