1. Please try uninstalling '[email protected]'. Just disabling extensions often doesn't get rid of their overhead.
2. The most likely explanation I can think of is: https://bugzilla.gnome.org/show_bug.cgi?id=781835 which is already fixed in Ubuntu 19.10, so please try that when/if you can afford a little prerelease risk: http://cdimage.ubuntu.com/daily-live/current/ 3. Another possible explanation is: https://gitlab.gnome.org/GNOME/mutter/merge_requests/189 which will soon be fixed in 19.10 after mutter reaches version 3.33.92 or higher. ** Bug watch added: bugzilla.gnome.org/ #781835 https://bugzilla.gnome.org/show_bug.cgi?id=781835 ** Changed in: gnome-shell (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1842369 Title: Gnome-shell hogs CPU Status in gnome-shell package in Ubuntu: Incomplete Bug description: Gnome-shell process spikes from 40-100% CPU usage on a 4-core processor without any extensions enabled upon start-up and just stays in that range.
