that applies to both machines. on the intel machine (i'm running sid on
it since december last year) i never experienced the problem before.

i did another two tests on the nvidia-based machine:

1. i used the xephyr x-server, which supports the composite extension
for x-clients and ran an xfce4-session in it: xephyr can redraw the xfce
terminal on the cpu faster than the "real" x-server with the nvidia
driver on the gpu!

2. i installed debian sid in a virtualbox-ose virtual machine, running
with virtualbox' "vboxvideo" graphics driver (it even supports
compositing! :) ). no problem to resize the xfce4-terminal window in
the virtual machine.

well, from these tests i dare to say this MUST be a bug in the
proprietary nvidia driver!

cheers - fuddl
