Large QQuickFramebufferObject slow down the scene graph thread using camera

Hi, I use Qml (Android) with the Camera/VideoOutput items and an embedded large QQuickFramebufferObject which contains the AR content. Now the behavior is the larger (amount of vertices) the QQuickFramebufferObject the more the VideoOutput starts to jerk, but the QQuickFramebufferObject stays smooth.
main.qml
Window { Camera { ... } VideoOutput { ... } Loader { active: true visible: status == Loader.Ready source: "qrc:/mdl/qml/fbo.qml" } }
fbo.qml
Fbo { anchors.fill: parent mirrorVertically: true }
Is there a way to control the framerate of the Camera/Videoutput from the scene graph thread somehow to make it more smooth?
