SVN commit 1167909 by graesslin:

Forward port rev 1167908
Revert rev 1137490: it caused compositing not working with legacy NVIDIA drivers and \
might be responsible for freezes when changing config. It can be reverted as there is \
already a better fix for buggy drivers present in 4.5.1. Did I mention that I love \
                drivers?
CCBUG: 243991
CCBUG: 241402
