    Description

      This not affects with 5.9.0 and 5.8.0. An example in attachment. 

      Here's main.qml from the attachment:

      main.qml
      import QtQuick 2.7
import QtQuick.Controls 2.1

ApplicationWindow {
    visible: true
    width: 800
    height: 600

    Timer {
        interval: 200
        repeat: true
        running: true
        onTriggered: {
            var tmp = fstImage.source
            fstImage.source = sndImage.source
            sndImage.source = tmp
        }
    }

    Row {
        Image {
            id: fstImage
            width: 400
            cache: false
            source: 'qrc:/images/arrow.png'
            fillMode: Image.PreserveAspectFit
        }

        Image {
            id: sndImage
            width: 400
            cache: false
            source: 'qrc:/images/back.png'
            fillMode: Image.PreserveAspectFit
        }
    }
}
