<pre>Based on your debug logs so far I have spotted one missed optimisation
opportunity:
commit f0565852b668832d4988e875bc12e23abb6e1829
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>
Date: Thu Apr 3 16:27:47 2014 +0100
sna: Short-circuit repeated clearing to the same color
Spotted in amongst a KDE debug log was a series of clear; copy; repeat
using Composite().
