Bug description:
  [regression] Compositing is jerky and stutters during touch events

  This appears to be a recent regression. In r1930 fingerpaint draws
  very disjointed curves on the N4. Going back just 10 revisions to
  r1920 however everything is beautifully smooth.

  Test case (on a touch device):
    1. mir_demo_server_minimal &
    2. mir_demo_client_fingerpaint -w
    3. Draw!
  Expected: Smooth curves.
  Observed: Irregular and disjointed curves.

  Update: Bisected. Found the regression happened in r1924.
