I have been having a problem with firefox since i upgraded to 2.0BETA.
I have the gtk2 version installed, though, the same problem exists with
the gtk1 version.

Basically what happens is, when i scroll down a page, there are
"residual lines" on the screen.  When i highlight the region with these
tracers on it, and click, the lines go away.  I have a feeling it is
something with my X installation (or rather, configuration), but i have
not seen this problem in any other app, so maybe it is just firefox.

Am I missing something in my XF86Config? an invalid option perhaps?

The machine is a g4 800 (quicksilver) with an ATI Radeon 7500 video
card.

Thanks for any help.
