[Bug 1513450] Re: higher than expected cpu for unity8

 

Testing mir_demo_server_minimal with mir_demo_client_egltriangle, I'm
seeing 30% CPU usage by the mir server just drawing a single spinny
triangle.

Testing a simple QML demo shell, we get same CPU usage as mir. So
punting to Mir team for investigation.
