On a fresh install of Ubuntu 19.04 on a 2019 Dell XPS 13, I have very high CPU usage from gnome-shell and Xorg (each one is taking up around 10%) when no other process is running. This increased greatly to more than 20% for gnome-shell when I enabled showing seconds in the top bar. After disabling seconds, I went back to ~10% cpu usage for each of those processes again. I opened this because most of the other relevant issues are closed, expired, or marked as invalid.
