    If I use ... what?  Not sure I know what you're referring to there.

    It's on-board video, based on the Intel i815 Chipset.  Whether I 
actually have the latest drivers, I don't know.  This is a freshly 
installed machine with all the updates applied.

    Not knowing what may be causing the artifacts, I didn't know where 
to start looking and/or prodding.  However, FC4 also comes with Remote 
Desktop buildin, which as I understood it, is not vnc, but it based on 
Microsoft's Remote Desktop.  If I use that with vnc-viewer, everything 
works fine.  No artifacts.  But the moment I use vnc-server, I get those 
artifacts.  I don't want to use the Remote Desktop feature because I 
would need to be logged on to the server for it to work, whereas with 
VNC, I just tell X to load the vnc module and I'm done.

W | It's not a bug - it's an undocumented feature.
