Description of problem:

I use a stock Fedora 18 driver for Radeon HD 5670 (ATI Redwood). When logging in into KDE the screen display what looks like a corrupted texture, flashes and then logs in successfully. Then KDE Crash Report Assistant reports that KWin crashed in r600_dri.so.


Version-Release number of selected component (if applicable):
$ rpm -qf /usr/lib64/dri/r600_dri.so
mesa-dri-drivers-9.1-3.fc18.x86_64

How reproducible:
Always.


Steps to Reproduce:
1. Reboot
2. Log into a KDE session
3. Observe a KDE crash report of KWin
  
Actual results:
KDE crash report of KWin

Expected results:
No crashes.
