      If Windows which is used Intel HD Graphics (please see attached qtdiag.txt) does not affected even ANGLE and software rendering.

          flags: Qt.Window |
                 Qt.FramelessWindowHint
      
          Rectangle {
              anchors.fill: parent
              color: "blue"
          }
      
          Window {
              id: win
              visible: true
              width: 320 + (60 * 2)
              height: 240 + (60 * 2)
              color: "transparent"
              modality: Qt.ApplicationModal
              flags: Qt.Window |
                     Qt.FramelessWindowHint
      
              Rectangle {
                  id: rect
                  anchors.fill: parent
                  anchors.margins: 60
                  color: "blue"
      
                  layer.enabled: true
                  layer.effect: DropShadow {
                      anchors.fill: rect
                      source: rect
                      horizontalOffset: 1
                      verticalOffset: 1
                      radius: 40
                      samples: 40
                      color: '#aa000000'
                  }
              }
          }
      }
      
      

      If Rectangle and DropShadow are put on singe Window, it works on any environment.
