Version 4 Beta performance issues

[James Weatherall]

David,

Glad to hear it's not a general 4<=>4 problem!

With regards to cursor-flashing - VNC 4 grabs the screen using a more
complete blit operation that the VNC 3 releases, which is necessary if
things like alpha-blended windows (Winamp3 and the like) are to be
visible.  A side-effect of this more complete blit from the main display
is that the cursor flickers while it's happening.

Cheers,
