Changing themes fixed this for me on Ubuntu 17.04, as per #3 above (Settings->Appearance->Styles).
Radiance/Ambiance themes: high cpu usage. All others: no problem. Other suggestions did not work for me: I don't have a ~/.config/gtk-3.0/*.css that was mentioned in #9. I am already using a Notification Area, as mentioned in #7. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1583164 Title: Panel Indicator uses 25% cpu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xfce4-indicator-plugin/+bug/1583164/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
