AnimatedImage uses a lot of memory when caching is enabled

      this will continue to allocate memory until it crashes. But not if visible.

      import QtQuick 2.7
import QtQuick.Window 2.0

Window {
    visible: true
    width: 640
    height: 680
    title: qsTr("QTBUG-64563")

    AnimatedImage {
        id: animation
        source: "miller.gif"
        cache: false
        visible: false
    }
}

      In my app this happens, not because my AnimatedImage is set to not visible, but because it is clipped or on a page that is not currently visible.

       

      example project attached.
