[Tournier Mathieu <mathieutournier@xxxxxxxxx>]

Public bug reported:

With ati opensource driver, when i turn on desktop effects in kde, when some effects are played (ex : wobbly windows) I see screen corruption in the windows diplayed (but not in plasma-desktop background, that's strange). When i turn them off all my desktop is displyed good.
Moreover, when I run bzflag (even without desktop effects) , all the content in the foreground flashes.
I had the same bug with xorg-edgers repository for lucid as soon I try a kernel = 2.6.35 (I forgot if this was in 2.6.34, but in 2.6.32 it worked good)

My config : dell xps 1640 with an ATI Mobility Radeon HD 3670 (M86)
