Description of problem:
On some webpages (not all) scrolling in Firefox produces horizontal line artifacts. See the attached screenshot.
It is reproducible both in Gnome shell and in XFCE.
This is a regression in 6.14.0-6* compared to 6.14.0-5*.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Go to http://www.svobodni.cz/ using Firefox
2. Drag the scrollbar down slowly.
image corruption as in the screenshot
no ugly horizontal lines over the webpage
Downgrading to xorg-x11-drv-ati-6.14.0-5.20110204gita27b5dbd9.fc15.x86_64 makes the bug go away.
Will attach dmesg and Xorg.0.log ...

can you get it at the default firefox zoom level (Ctrl+0)
or does it only happen if you zoom in?

Yes, I had it zoomed in a bit without realizing it. There's no corruption with the default zoom level.
6.14.0-7 fixes the bug. Thanks.
