Might try some of the VNC encoding options, like those at:
Assuming you're using a Unix domain or localhost socket, the "raw"
encoding might be best, with # colors matched to the source/dest.

This is a feature of vnc -- since the "remote system" cursor may lag
your local cursor, VNC represents your local cursor with a small box,
so that any mismatch between local and remote cursors is obvious and
visible.  The "UseLocalCursor" option to VNC should affect this.  (You
also might want to look into AutoReconnect.)

I'm using the names of the options in the "official" vnc viewer, but I
think the open source ones have the same options, maybe spelled
somewhat differently.
