On my Compaq Presario X1000 laptop with ATI Mobility Radeon 9000 chipset, I am getting corruption of text displays with garbage lines of pixels above the characters in some situations. Will attach screenshot.
This is with xorg-x11-drv-ati from Fedora 10: xorg-x11-drv-ati-6.9.0-63.fc10.i386
With Fedora 9 which used the 6.8.0 driver I did not see this problem.

See the junk pixels in the first body text under "Comment #9" and in the header text for "Comment #10".

Xorg.0.log from X startup
Does it still happen with 184.108.40.206 or current xf86-video-ati Git?
Does Option "RenderAccel" "off" work around it?
Disabling RenderAccel appears to work around the problem. I will try and get a newer version of the driver built and try that.
Current git does not appear to have the problem.. question is if there's a patch that could be backported into the Fedora 10 version..

git bisect should help isolate the change that fixed it.
I don't think so, that commit refers to this Fedora bug:
which states the patch is in xorg-x11-drv-ati-6.9.0-61.fc10, so if that fixed it I would not be seeing this problem. Also that refers to EXA only, whereas this problem shows up in both XAA and EXA.
No longer a problem in Fedora 11.
