I am running a ubuntu 10.10 machine which is controlled remotely via the vinagre client installed on another machine running the same OS. The problem is that there is a significant delay in pointer movements when the remote machine has compiz enabled. However using metacity things are very smooth. Is it a problem with compiz, vinagre or something else?
This is a common issue with VNC protocol and Compiz. Most recommendations for this are to add a button to switch between Metacity and Compiz. You may also be interested in the list of best VNC Clients for trying alternatives.
