Here is the log of one sleep and wakeup where I had the issue:

   [130048.797062] PM: suspend exit

Unlike I seen before, fvwm2 is also affected. Also it is not that
relyable to reproduce. Some times it needs extendet sleeping time and in
the other moment it happens directly after going to sleep.

It looks like the display is drawed in the wrong direction, first the
blacking out from the screensaver and afterwards the content of my
desktop gets drawed above it. And when it happens, it is pretty slow
(for that machine). It takes about one or two seconds.

Note also that there is no S3 on that system available. The system only
went to S2.

Regards
   Klaus
