Bug Description
Performance regression: mir_demo_
This is building Mir from development-branch. I've verified the bug occurs in r1117 right up to r1207 on trusty (I only noticed it after upgrading to trusty). So it looks like a regression at a lower layer... Mesa or the kernel.
Regression relative to how it performed in saucy, I mean.

I'm also seeing a massive performance regression with flicker and fingerpaint (software renderers) on Nexus 4 using trusty images. Not sure if it's the same bug.
