    Description

      Resizing a QQuickView by way of animating the height of its content worked flawlessly in Qt 5.3.2.

      In Qt 5.4, it appears to cause significant visual glitches and flickering.

      I have attached two short videos clearly showing the problem. The effect is somewhat different when using debug and release builds, the two videos demonstrate the problem in both environments.

      To resize the QQuickView, a SequentialAnimation containing a NumberAnimation targeting the height of the share bar item is triggered.
