[R500 x1400] Form check-box corruption in Firefox [Human GTK-theme, EXA enabled]

[Øyvind Stegard]

Binary package hint: xserver-xorg-video-radeon

When scrolling a web page in Firefox that has check-boxes in a form, I frequently observe slight graphics corruption under some of the check-boxes. The corruption is typically black pixels. Hovering mouse over affected check-boxes makes it go away (presumably because this triggers a high-light redraw).

Xorg driver in use is xserver-xorg-video-radeon git20081003.f9826a56-0ubuntu2.
EXA-acceleration is enabled.
Ubuntu 8.10 (fully updated, installed from RC).
Compiz is enabled.
GTK theme is Human (Ubuntu default).
Graphics card: ATI X1400 mobile radeon (R500), 128MB RAM.

I will attach the following:
* Screenshot which shows the problem
* Kernel log (dmesg)
* Output of 'lspci -vvnn'
* Xorg.0.log
* xorg.conf

If more information is needed, please say so. I am also willing and able to test new GIT-snapshots of the radeon driver, and provide feedback if problems are fixed, etc.

The same problem applies to radio-button widgets.
