Description: Ubuntu 18.04.1 LTS Release: 18.04 2. gnome-system-monitor: Installed: (none) Candidate: 3.28.2-0ubuntu1 Version table: 3.28.2-0ubuntu1 500 500 http://us.archive.ubuntu.com/ubuntu bionic-updates/main amd64 Packages 3.28.1-1 500 500 http://us.archive.ubuntu.com/ubuntu bionic/main amd64 Packages 3. I expect the colors to update in the graph and persist across application exit. 4. When I choose a different color for my cpu graphs the color does not update in the actual graph. Also when I close the app and open it again the colors seem to reset to default. Screenshot attached.
