    Description

      Bug exists only in Qt 5.5, it does not exist in Qt 5.4.2 or lower.
      Try example below. 

      ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")
    //flags: Qt.Window | Qt.WA_OpaquePaintEvent | Qt.WA_NoSystemBackground

    Image
    {
        anchors.fill: parent
        source: "qrc:/C:/Windows/Web/Wallpaper/Windows/img0.jpg"
    }
}

      Image flickers during resize window using bottom or right border.
      On my system bug appears on Windows 7 SP1 x64, Fedora 22 (Gnome, KDE). On Windows 8.1 it is almost invisible.
