Description steve szmidt 2008-07-18 19:30:25 UTC 
Version:            (using KDE 3.5.9)
Installed from:    Ubuntu Packages
Compiler:          Ubuntu 4.2.3-2ubuntu7 
OS:                Linux

When using three or more screens the 1st screen gets an overlay from each additional screen background onto itself as soon as the desktop is fully painted after login.

I have three screens: Screen0 is 3840x1200 from a twinview of two 1920x1200.
Screen1 is 1280x1024 and screen2 is 1440x900.

Screen0 will get the default desktop from screen 1 and 2 the moment it has completed drawing screen0. All icons in place and so on.

I thought it was the nVidia driver, but since it only appears the moment KDE desktop is done painting the desktops I'm guessing it's KDE. It's almost as if they were sharing desktop buffers.

I managed to get rid of the additional backgrounds by renaming the .kde directory and let it make a new one. However nVidia's has a configuration tool which identifies each screen. That number is drawn in the middle of each screen.

It identifies the center of screen 1 and 2 as being in the middle of where the two desktops of screen 1 and 2 where painted, on the left monitor of screen0.

Kdesktop is no more mantained. Fortunatly this bug seems not to be valid for
KDE 4. Please reopen if this bug is not a kdesktop one (and it is not solved)
or it can be reproduced on KDE 4.

Thanks.
