ALMOST black?

Does the program window stop responding? Have you tried killing X?
Maybe that's not as drastic as rebooting (except of course the
system completely refuses to respond, which you didn't mention).

Have you tried to temporarily use a different, more simpler
window manager (simplest idea: twm) to see if this might be
related to KDE?

I'm using several Gtk applications here on WindowMaker (so
no full KDE desktop), and _sometimes_ I have Firefox freezing
the whole system; it stops during drawing operations (!) and
the only help is to power off the machine. But in my case,
I'm quite confident it's related to a malfunctioning graphics
card -- also nVidia card + proper driver. However, this does
not happen to other Gtk applications (such as Sylpheed), only
to Firefox (and games such as Doom 3 demo and Quake 4 demo,
but not to OpenArena).
