Remote Desktop flicker

When remoting to another computer, I get something similar to a flickering.

It's really noticable with the CPU usage gadget. I can actually see the redraw of it.

Also on text lists, it's like the remote system is refreshing the list then slowly redrawing it almost every second.

Any clues?

Thanks, Nos. Have the experience set to max and all since I'm connecting over a gigaLAN.
