I had the same problem, and my computer graphics felt slow (i.e the side bar opening animation). I had fixed this by messing with the nvidia drivers, using prime-select to select nvidia, etc. However after update plus restart, this started to happen again.
I noticed gnome-shell always at 30% more or less. I disabled the extension "Vitals" but had the same issue, and disabled all extensions and the issue persisted. So I logged out and in again, and it started working correctly. I re-enabled extensions minus-vitals, and so far it is working correctly with the animations -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1974054 Title: Without a reason gnome-shell CPU usage gets high To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1974054/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
