Yes it does normally jump to around the correct time, but at the same time it 
can be displaying several windows, each logged in to other computers via SSH 
and each running top updated normally, so the screen is being refreshed 
normally.
I have also noticed that KDE can appear unstable, I have multiple KDE desktops 
running, and sometimes get windows jumping between different desktops.
It is a fast computer with plenty of RAM.
