When running Gnome 3 in Wayland mode (confirmed with XDG_SESSION_TYPE
env var) I see the following issues on this hardware:
* Jerky animations (glxgears stutters noticably)
* Mouse cursor sometimes updated at a reduced framerate, usualy when CPU is
under load, appearing to worsen over time (> 8 hours uptime)
* High CPU usage when mousing over icons in left-hand side Unity dock (20-30%),
also causing mouse cursor to stutter
* 15fps in Kodi and poor video playback framerate
* 30-40% CPU usage in Kodi when program idle
* Gnome shell frequently using 25% of CPU or more
All issues disappear when using x11 mode (again confirmed with
XDG_SESSION_TYPE env var). Performance in that case seems as good as
17.04
