Disable or enable TearFree updates. This option forces X to perform all
rendering to a backbuffer prior to updating the actual display. It requires

copy, and requires Damage tracking update. Thus enabling TearFree requires more
copy, and requires Damage tracking. Thus enabling TearFree requires more
memory and is slower (reduced throughput) and introduces a small amount of
output latency, but it should not impact input latency. However, the update to
the screen is then performed synchronously with the vertical refresh of the
