after another few days of testing I found a workaround.
The cause of these problems seems to be the xorg-driver, not kde, gnome, etc.
I created the file /opt/ltsp/i386/etc/X11/xorg.conf in the thin client image
with this contents:
Section "ServerFlags"
Option "AIGLX" "off"
EndSection
This switches off 3D-Acceleration for the X-Server of the thin client.
Additionally you have to configure in lts.conf:
X_CONF=/etc/X11/xorg.conf
This tells the X-Server to use this xorg.conf file.
This setup workes for my test environment. I currently don't have any
experience with other hardware (the thin client is VIA-based). It would be
interesting if it also works for you.
This whole wisdom is of course *not* base on my own knowledge. I found the
final hint here:

Unfortunatelly (for you :^) it's in german.
Viele Grüße
Helmut
