Screenshot of picture displayed in firefox and scrolled vertical and horizontal
several times

For some time now I get corruptions within several applications when scrolling.

Those applications include e.g. Firefox, Thunderbird, Gimp, Inkscape, Konsole
(KDE4).

Applications that *seem* to be safe include Gwenview and Dolphin.

Those corruptions (as seen in the attached screenshot) appear with different
kernels:

- 2.6.32+drm2.6.33 (Ubuntu Lucid)
- 2.6.33 mainline
- 2.6.34-rc2 airlied
- 2.6.34-rc3

So I think this is related to the driver and not the drm kernel part.
