Public bug reported: Added some gnome extensions, but this was always present. Maybe the multi monitor setup is at fault?
Attached output is from running 'sudo strace -p' on gnome-shell. The whole FUTEX part in the middle is only observable during one of these "stutters". The parts before and after is just to show what "normally" is going on. I have no idea what any of this means. I hope this is somewhat useful.
