Comment 0 for bug 1070735

When Unity UI elements - the alt-tab switcher, or the top bar shadow - are above an unresponsive window, the portion of the Unity elements which are above the window flicker in and out of view.

Although the attached video doesn't show it, this behaviour still occurs if the unresponsive window is not visible - the Unity elements over where it is still flicker.
