Compiz w/ kde screensaver blanks 1/4 screen

I noticed while trying to narrow down a plugin that disabling and re-enabling certain plugins in the window section will cause it to work right once, but then on subsequent ctrl-l it does the 1/4 screen again.

The patch below (that will be part of kde 3.5.8) fixes the issue:

grabbed, thanks.

The patch is against kde, so I close the compiz task.
