I haven't seen any reports of gnome-shell misbehaving like this in a long time.
Firstly make sure you're not using any non-standard extensions (it looks like you're not?). Look in the 'Extensions' app. Second, how populated is your desktop (assuming you're using the Desktop Icons NG extension)? I haven't seen any issues with the current extension but its predecessor did have problems like this when the Desktop directory or its contents were touched regularly (log files etc). The only other cause I can think of would be an expensive garbage collection run. Again, that's usually only a problem when people install non-standard extensions. And your memory usage looks quite normal (heap RSS is 184MB) so I wouldn't imagine garbage collection performance is an issue here. So other than the usual stuff above, you might have discovered a busy wait in gnome-shell or mutter. I would recommend: 1. Verify the bug occurs with ZERO extensions (no Ubuntu ones either) and then 2.
