I have the same problem with two Ubuntu 11.04 machines. I'm sure it's only the vino server at fault, as there was no problem when the server machine (my mother's) was still on 10.10 yet the client machine (mine) was already on 11.04. When my mother upgraded to 11.04 yesterday, I can no longer help her via VNC. Her screen won't repaint in my viewer.

We seem to have regressed to a previous problem of desktop effects with VNC not repainting the screen. When we first installed 10.04 on the two machines a while ago, we had to turn off desktop effects for VNC to repaint the screen. However, an Ubuntu update was installed at some point and we could then have desktop effects on plus use VNC. We can't turn off desktop effects with Unity.

Could this be related/similar to this bug?: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/353126
