vnc screen corruption in FC4?

[mike cohler]

After installing FC4 on two machines (clean installs) it was noticed
that getting VNC loaded on the server machine by
editing /etc/X11/xorg.conf to include 'load "vnc" ' and an appropriate
password option line, gave screen corruption when connecting from a vnc
client machine (also running current FC4), whenever the mouse was moved
or keys were clicked. 

In this case vnc was running in an ssh tunnel. The identical setup was
used without previous problems with FC3.

This has been reported in bugzilla at
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=162304

Has anyone else seen this problem using FC4 machines, and if so have you
managed to solve it?

Or will we have to wait for an update rpm? I note that there is a
version of vnc and vnc-server on the development list for rpms as 
vnc-server-4.1.1-14.i386.rpm
and similar for vnc itself.

Has anyone tried these in FC4 ?
