I am seeing the same bug in Hardy when i connect to a secondary viewport.
I have 2 monitors configured as 2 independent displays.
I am normally able to access them via vnc as hostname:0 and hostname:1 alternatively hostname:5900 and hostname:5901
If I enable visual effects, the second view port no longer updates within VNC exactly as described in this bug.
If I disable visual effect, everything goes back to normal.
