      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.
