Public bug reported: I am experiencing 60% - 200% CPU utilization after an upgrade from ubuntu artful to bionic.
Pretty much any drawing results in a sluggish behavior due to high CPU utilization. The same combination of kernel/drivers did not result in the issue on 17.10 so gnome-shell seems a good candidate to blame.
