[kde-linux] Desktop Sharing uses lots of CPU

[Jerome Yuzyk]

[KDE 3.5.4 on Fedora Core 5]

I am getting 85% CPU on the server when using Desktop Sharing on a Sempron 
3100+ machine with an nVidia GeForce 6000 with nVidia's latest driver. I'm 
using VNCviewer on the client side, and had to set Hextile encoding to 
avoid a "Rect too big" failure. Is this an nVidia thing, or is there a 
better way to set up?
