      Widgets now receive two move events per move. The first (correct) one is synchronous with the move and reports the correct pos and oldP. The second one occurs during the next event loop due to QGuiApplicationPrivate::processGeometryChangeEvent() and has incorrect coordinates, perhaps due to the offset of the title bar.

      I've attached a small example app.
      Note that this is a possible duplicate of bug QTBUG-25631, but I am experiencing this issue in Qt 5.1, though I was not experiencing it in Qt 4.8.x
