           Summary: corrupted background on logout screen
           Product: plasma
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: panel-devel kde org
        ReportedBy: ambro b4ever net


Version:            (using Devel)
Installed from:    Compiled sources

When I choose Leave->Logout in the menu, the logout dialog shows up, however the background shows garbage. Only a small part of the background on the top of the screen which gets black and-white as supposed is displayed correctly. The rest of the background is a black-and-white image that seems to have been produced by combining random parts of my current screen and even parts of the screen in the past, and it changes only slightly during the darkening time.

This does not happen if compositing is enabled.
Graphics card is Nvidia 8800 GTX with driver version 173.14.09.
