The smells like Nagle, but who knows.... Can you give information on
your connection parameters. For example: I'm in a LAN and noticed that I
get the best results using no compression (rgb) - but one in a while
there are small errors in the disply (e.g. an immage not being updated
correctly) - opposed to png. I also have the gnome-system-monitor-applet
running, therefore data is sent continuously. I would also be interested
whether the whole screen hangs (e.g. including the system monitor) or
only the single Applicaiton. Maby you cold start xkbwatch and see,
whether the keystrokes (e.g. shift ) still arrive at the server.

Cheers
Morty
