I don't have Ubuntu 11 around to test, but can you try disabling visual effects? (somewhere in the Appearance preferences). Let me know if it helps.

Removing desktop effects does fix the problem for me.
Found here: http://www.ubun2.com/question/379/wh...w_and_unusable a solution for me.
In terminal, write the command:
gconf-editor
Then navigate to: desktop / gnome / remote_access. Enable the "disable_xdamage" setting.
I have used Ubuntu 9.04 through 10.10 and all worked very nicely with the VNC server. I could log in from home with a Windows machine no problem. After upgrading or installing fresh Natty 11.04, VNC server does not work at all. This is on multiple machines. It either comes up with an error after waiting a long time or indicates the VNC server cannot start on the port (no matter which port I use!). Changing back to the Classic desktop does not fix it; this is a problem with 11.04 and is really irritating!!
BYW- tried to enter a bug report but launchpad would not accept my password(?)
Very frustrated!
I've been seeing this VNC slow screen re-drawing on 11.04, but I changed to "Ubuntu Classic" on the login screen and that solved it, back to normal re-draw speeds.
I'm just using VNC Viewer 4 from a WindowsXP machine from connected locally via 100MB Ethenet

I believe this can all be lumped in to the general compiz/vino problem that cropped up a few releases back.
You mention the 'disable_xdamage' solution, but this is only a band-aid fix. What disabling xdammage does is make vino send an entire image of the screen on every refresh. As opposed to simply sending the portions of the screen that have moved/changes (as it normally would). If you're on the same LAN as the remote machine this may be acceptable, but across the internet? You may get one refresh per second... disabling compiz is the only 'solution' I've consistently seen fix the problem for people.

Please contribute there.
Just upgraded 3 three computers over the weekend from 10.4 to 11.4 all running classic, no effects etc (when I say upgrade I mean re-format and 11.4 install)...still VNC refresh issues, simply put there was no workaround for me....re-installed 10.04 back on them and VNC works again.
Hope they fix the bug soon.
