i think we should pass the lastVsynctime to animate as well...


can you also fix the routing in threadproxy for beginFrameAndCommit's timestamp?
that should also be lastVSyncTime instead of now...

I think you are right, but I'm not sure what side effects this could cause.
Maybe it's better to do this in another patch.

     if (drawFrame) {
-        m_layerTreeHostImpl->drawLayers(frame);
+        m_layerTreeHostImpl->drawLayers(frame, m_schedulerOnImplThread->lastDrawTime());
         result.didDraw = true;
     }
     m_layerTreeHostImpl->didDrawAllLayers(frame);
