Image disturbances (KDE Kickoff)

Update the xf86-video-ati from version 6.13.2 to 6.14.0 results in image
disturbances on the KDE desktop.

Steps to Reproduce (on my computer):
PC configuration: Radeon HD5830, AMD X6, dual screen both over DVI
1) Update xf86-video-ati from 6.13.2 to 6.14.0 on 64bit Arch Linux
2) Start KDE (kdm)
3) User login

Actual Results:
Image disturbance in KDE, see attachment

Expected Results:
Nice KDE desktop

Build Date & Platform:
Fre 04 Feb 2011 14:05:30 CET (xf86-video-ati 6.14.0)

Additional Builds and Platforms:
Doesn't occur on build xf86-video-ati 6.13.2-2 (Arch Linux version) build date
Sam 09 Oct 2010 15:52:37 CEST

Additional Information:
+ Add Option "EXAPixmaps" "Off" to xorg.conf resolves the image disturbances,
but KDE slows down and other screen refresh disturbance occure
- Clean pixmap caches (kpc directory in /tmp/var and ~/.kde4) in KDE doesn't
solve the problem
- Turn on/off KDE composite doesn't solve the problem
+ Reinstall xf86-video-ati 6.13.2-2 resolves the image disturbances
