Same issue here with a Radeon HD 3870 (RV670 ?), KDE 4.2.x
(desktop effects disabled) and latest radeonhd and drm from git
with DRI enabled.

I didn't experiment this problem when I was using radeonhd 1.2.4
(without the r6xx/r7xx acceleration support).

My other computer which is also running KDE 4.2.x with a NVIDIA
GPU does not have this issue.
