It appears the high CPU of gnome-shell with totem on Wayland at least is due to the totem app window redrawing at 60Hz seemingly only on Wayland (bug 1698282). When this happens, the compositor will have to upload (copy) the window texture from CPU to GPU 60 times per second, which is CPU-intensive. This would happen with any software ("shm") surface that is large and redrawing frequently. So I guess that might include Firefox too.
