      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
              }
          }
      }
