Definitely a regression. I used Remote Desktop with Ubuntu 8.10, 8.04, and 7.10 and UltraVNC client on Windows without issue.

Confirmed - Clean install of 9.04 - VNC client shows initial screen but no updates. Clicking Refresh button in client doesn't refresh the screen.

Confirmed - I am using NVIDIA restricted driver and "Extra" visual effects.

Confirmed - setting visual effects to "None" restores display updates to VNC client.

Interesting behavior - With visual effects set to "Extra", I was watching both computers. The VNC client was able to control the Ubuntu 9.04 desktop correctly, but the screen updates weren't being updated in the VNC client. The VNC server appears to work correctly except for the screen updates w/ compiz enabled.
