Title:
  Compiz running on Intel Haswell GPU has 100% CPU usage when computer
  is locked

Status in Compiz:
  New
Status in compiz package in Ubuntu:
  Confirmed

Bug description:
  I have Ubuntu 14.04 installed on a Lenovo X1 Carbon series 2. Whenever
  I lock my screen, compiz's CPU usage goes through the roof and it
  causes the CPU fan to spin up to max speed. I SSH'ed into the machine
  while it was locked to verify that it was indeed the compiz process
  causing the high cpu usage. When I unlock my computer, everything goes
  back to normal.

  I've looked at
  https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/969860, which
  seems related but that is for fglrx. This laptop has an Intel Haswell
  gpu.
