kwin: All windows redraw when moving or resizing a window

Hi, 
I have a problem with a remote xwindows connection running
kde. 
It runs on Reflection X in xdmcp mode (gdm login). 
Each time I move or resize a window in kde all other windows
and icons are 
redrawn in kde. 
This doesn't happen in a gnome session (even when I run e.g.
konqueror in the gnome session).
The server has kde 3.3.1 (RHEL-4) installed. 
It also doesn't happen on on older version of kde (3.05a)
runnning on Red Hat 7.3.


Apparently it is kde's window manager (kwin) which is
causing the problem.

When I set the environment variable KDEWIN to metacity
(setenv KDEWIN
/usr/bin/metacity) which is the default gnome window
manager, then
everything works fine. I also tried it with the wmaker
window manager
and then the problem is also gone.

Reflection X normally uses the default window manager of the
remote
server. But you can force it to use a local window manager
and then the
problem is also gone.



So what is the kwin window manager doing wrong here?
Is there some workaround?

Thanks in advance, Wim

 That's rather old. Can you reproduce the problem also with
KDE3.5.6?
