Ultra encoding + Track Remote Cursor Locally combination of settings will cause vnc viewer to hang.
To reproduce:
1) Configure VNC viewer to use the Ultra encoding.
2) Cursor handling mode must be set to Track Remote Cursor Locally
3) Connect to a VNC server. In order to reproduce the issue some screen activity should by happening on the server side.Just play c:\windows\clocks.avi in the Media Player for example.
4) Hover mouse cursor over the viewer window.
I'm getting hang within seconds. It seems like there is a deadlock that occurs during screen updates processing and cursor updates processing.
