First time up, system monitor is fine, with a red line. I don't like red, so click on the little color button below the CPU History to change it. No problem yet, except it's still red; I presume setting doesn't take immediately, still no problem. Close, reinvoke, it's now black. No matter what I do it stays black. White background works to some extent so there is a workaround. Reproducible: Always Steps to Reproduce: 1. gnome-system-monitor 2. change CPU history color to any color other than black 3. close, then reinvoke gnome-system-monitor Actual Results: black colored CPU History line Expected Results: It should have taken the suggested color from the button below the graph, either immediately or after reinvoke of the system monitor.

confirmed on 2.4 , but works in the (2.5) dev version. If you can find the patch/bug/etc we could apply the patch in the 2.4 series for now.
closing, since it is fixed in a newer version in the tree
