Bug description:
  I noticed my laptop fan going crazy while the screen is locked. But
  logging in via ssh showed it's mostly CPU-idle according to top.
  Powertop on the other hand shows compiz is spinning at 200 wakeups per
  second.

  I seem to recall that 200 Hz is the upper limit in Compiz, designed to
  throttle it when SwapBuffers is failing to so.

  Maybe we need to do some work in our Mir client logic for SwapBuffers
  then. As I am using XMir and unity-system-compositor.
