I cherry-picked this patch into the source code of
2.13.0, as provided by the debian package
xserver-xorg-video-intel version 2.13.0-5.

With that patch applied, I still observed the described behaviour.
Additionally, some java application had display update problems. (But
java generally has some problems because I'm using a non-reparenting
window manager, 'awesome', which java doesn't like).

What do you think, would it be worthwhile to try a more recent version
of xf86-video-intel?

Jan
