It seems this was a problem with older Catalyst versions and judging by
the last comments seems to be fixed by now. I no longer have an AMD GPU
so I can't test this, so if anyone else could test it we could move this
bug forward.

Title:
  OpenGL windows always on top with Unity-2D and fglrx driver

Status in Unity 2D:
  Confirmed
Status in “unity-2d” package in Ubuntu:
  Confirmed

Bug description:
  When running an OpenGL application with Unity-2D (3.8.4.1) there is visual corruption in certain situations. So far I identified the following problems: 
   - if the launcher covers any part of the OpenGL application's window, it will flicker when appearing and disappearing and may even become totally invisible (behind the OpenGL window?)
   - dragging a non-maximized OpenGL application's window will cause severe flicker inside the application itself

  My system is Ubuntu 11.04 using the latest 11.6 version of fglrx and I
  still haven't tried with the free Radeon driver. Will report back as
  soon as I test that. There is no corruption when using normal Unity.

  Steps to reproduce:
  1) open an application that makes use of OpenGL acceleration and can run in windowed mode (e.g. glxgears, blender)
  2) make sure that the application's window can be covered by the unity launcher
  3) move the mouse to the top left side of the screen so the launcher appears

  Expected results:
  There is no corruption  in the areas where the launcher intercepts the application's window

  Actual results
  Visual corruption in the areas where the launcher intercepts the application's window
