      Using QSG_RENDER_TIMINGS, or the qmlprofiler, I notice the scene graph is swapping frames even if the AnimatedImage is invisible, a workaound is to bind playing: visible

      Only happens with basic render loop, this then becomes a scene graph issue, but there's also the fact that AnimatedImage calls update() even if invisible

       import QtQuick 2.6
 import QtQuick.Window 2.2

Window {
     visible: true
     width: 640
     height: 480
     title: qsTr("Hello World")

 

    AnimatedImage {
         id: anim
         source: "https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif"

         width: 400
          height: 400
          playing: true
          visible: false
     }
 }
