Perhaps you could check the MTU of your machine and the remote host? We
have had problems with VNC displaying similar behavior because the MTU's
didn't match. To diagnose, you run a ping with varying sized packets
between the hosts and tcpdump the traffic in very verbose mode. That way
you get the packet sizes being reported.


may not be your problem but it is a suggestion ay ;)

Also check to make sure that VNC is actually listening on the port you
think it should be. You can netstat -npl to check for that.

good luck,gb
