I'm not sure I can work on this while I only have one laptop on hand
this week. I am getting highly erratic benchmark results where a bare

I can reproduce this bug in Xorg sessions with Intel graphics. My
fullscreen benchmark results are about a quarter of what they should be
when mutter/gnome-shell is running. 4x performance is achieved by
running on a bare Xorg server without mutter/gnome-shell.
