Mutter 3.33.92 will improve performance again when it is soon available, but that might not be the problem here...
Please start by uninstalling/deleting (don't just disable) all the extensions you have: '[email protected]' '[email protected]' '[email protected]' '[email protected]' 'desktop-icons@csoriano' '[email protected]' '[email protected]' '[email protected]' and then tell us if the problem persists. We need to exclude extensions from the equation first, since we find so many bugs are caused by extensions. And you do need to uninstall them since they can still affect the system even when disabled. ** Tags added: performance ** 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/1842890 Title: gnome-shell high cpu usage and unresponsiveness Status in gnome-shell package in Ubuntu: Incomplete Bug description: From time to time the shell becomes slow and poorly responsive, checking the CPU usage I discovered that in such moments it had high values, like 25-35%. In only one occasion it went up to 100% CPU and I was forced to reboot. I don't know if it matters, but I'm using an external screen connected to my laptop. Let me know if I can help better to debug the issue.
