Looks like manual vsync ticks are not generated when scheduler is updating resources. This happens when there's nothing to draw but resources to update. To reproduce go to a page that generates more than 48 resource updates per frame. E.g. http://www.corp.google.com/~reveman/texture-uploads/test.html with the browser window relatively large. Or it will reproduce on any composited page after lowering the textureUpdatesPerFrame constant in CCTextureUpdateController.cpp to 5.
