System monitor takes 50% CPU

[Jetero]

Every time I start the system monitor my computer slows down DRAMATICALLY. I get constant 50% CPU usage, and no matter what I click it takes 7-8 seconds to respond. When I close(it is nerve cracking) system monitor everything goes back to normal. BTW I love the new look and feel of Ubuntu. THUMBS UP

I have similar symptoms. If the System Monitor window is resized to the smallest possible size, the CPU usage drops to between 7 and 10%. If i maximize the window, it quickly jumps to +60%. I have the same issue on 2 similarly configured machines, both running 8.04 beta.

The window size relationship causes me to believe the custom graphing/plotting widgets used by gnome-system-monitor are the source of the problem, but watching top, i can see it's my Xorg process that is occupying the cpu resources.

Separately, the new gnome-system-monitor shows only one cpu on both my quad and dual cored systems. Is this related to the completely fair scheduler? could this be related to the bug we are seeing?
