Wrong behavior QWidget::move in the mixed retina and non retina displays.

If the window (in my case is QGLWidget as top window) is created on the retina device but then by QGLWidget::move(QPoint) method move to the non-retina device - get a wrong behavior. If window on the non-retina display after each call move() is the real value of QWidget::y() coord is less in half-height of window (or other values, it depends of the settings of retina display). X coord have right value.

if move the window by titlebar, all looks fine.
