Bug description:
  Nested servers periodically stutter (half frame rate) with Mir 0.26.1

  On an old laptop, it's about half the time stuttering and half the
  time smooth.

  On a fast desktop, it only stutters occasionally like when a large
  blur is active.

  It seems the problem is Mir's predictive bypass optimization
  conflicting with the new client-side vsync optimization. Both are
  correct and desirable when used alone, but when used together they
  conflict, presumably because the former requires perfect vsync phase
  and the latter lacks correct vsync phase (which is still an exercise
  for later).

  A workaround to get more reliably smooth frame rates is to create a file:
/etc/lightdm/lightdm.conf.d/foo.conf
  with contents:

  [Seat:*]
  unity-compositor-command=/usr/sbin/unity-system-compositor --composite-delay=0
