I've seen this with various combinations of software running on X11, and 
the X11 driver itself. When changing between drivers, I've seen it cure 
one app and make another take on the new trait. I believe there is some 
sort of caching or "don't-redraw-what-hasn't-changed" code that doesn't 
work quite right. No idea how to solve it, but others have mentioned 
trying FC6...different distros using the same drivers has worked wonders 
to repair some of these.
