Ubuntu Unity-3D & Qt 5.3 redraw problems

  • I am observing problems where QtQuick2 (Qt 5.3) applications running on Ubuntu 12.04 don't redraw when they are dragged. I isolated the problem to running Unity-3D mode (not to be confused with Unity3d Game Engine!). When I log in selecting Unity-2D mode, everything works fine.

    The problem behavior is when applications are dragged, the app window is filled with whatever is beneath the app and doesn't refresh to the actual application contents. Note that if an item item changes in the QML scene graph, everything redraws and looks fine. Also note that I see the problem with any QML application, including the Hello project.
