Having the same problem ...

The following happens:
1) Log in - compositing has been disabled (and cannot be re-enabled if I
   remember correctly)
2) Then log out - display freezes (black screen/displaying terminal content/...).
   The system can still be rebooted using SysRq combinations/executing
   "sleep 300; sudo shutdown -r now" in a terminal before triggering the crash/...
3) Reboot and log in again - one plasma panel is corrupted (see screenshot), the
   other one looks as if compositing was disabled (according to the settings it is
   enabled though); after toggling compositing, the panel is displayed correctly


Backtrace of one crash (diff of kdm.log before logging out and before
rebooting, i.e. after the crash):
