2 QML windows with continuous animation not rendering on IMX8 as expected

I have a QML application where in I have two windows. I have an image with continuous animation on each window. The expected result is to have two windows with an image rotating 360 degree continuously. The result is as expected on Desktop. But on IMX8, I am able to see two windows with an image without rotation animation. My code is as shown below:

main.qml

Code:

---

import QtQuick 2.12
import QtQuick.Window 2.12
 
Window {
    id: root
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
 
    AnimationWindow {}
 
    Window{
        id: child
 
        width: root.width/2
        height: root.height/2
        visible: true
 
        AnimationWindow{}
    }
}

AnimationWindow.qml

Code:

---

import QtQuick 2.0
 
Item {
    property bool running: false
 
    Rectangle {
        height: root.height
        width: root.width
        anchors.centerIn: root
 
        Image {
            id: bg
            source: "qrc:/Images/FaultAndWarningStop.png"
            height: parent.height
            width: parent.width
            fillMode: Image.PreserveAspectFit
 
            RotationAnimation on rotation{
                from: 0
                to: 360
                duration: 3000
                running: root.running
                loops: Animation.Infinite
            }
        }
 
        MouseArea{
            anchors.fill: bg
            onClicked: root.running = true
        }
    }
}

The output seen on IMX8 is just 2 static images on each window rather than with rotation. Is there any issue with QQuickWindow continuously updating on IMX8?

Thanks in advance!
