Currently frame instrumentation only works for Blackberry (and for Chromium in Blink) We need to support it in coordinated graphics for Qt/EFL, by calling the right functions from CoordinatedLayerTreeHost and enabling the flag.
Created attachment 202413 [details] patch Overrode supportsFrameInstrumentation in order to enable frame instrumentation on ports that use coordinated graphics. didBeginFrame() needs to be called to render bars.
