I removed the non-Ubuntu extensions (including user-theme, which is provided by the gnome-shell-extensions package).
Should the problem happen again, would you like me to apport collect or to just write it? -- 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.
