Description Gene 2014-01-05 08:29:34 CET 
Earlier bug 532 (https://jogamp.org/bugzilla/show_bug.cgi?id=532) now occurs in Mac OS X Lion and Mavericks.  

Once a GLCanvas overlays a lightweight Swing panel, it never can be reordered below it again.  This is a z-ordering problem.

The sample code in 532 has a CardLayout with a JPanel for the top card and GLCanvas for the bottom.  

Press the button and the GLCanvas with rotating square animation comes to top.  Press it again, and the JPanel should come back.  

It does on 32- and 64-bit Windows platforms with JRE 6 and 7.  Not with Mac under JRE 7.

Can you reproduce with the derived unit test ?
  com.jogamp.opengl.test.junit.jogl.acore.anim.TestAWTCardLayoutAnimatorStartStopBug532

I double check w/ latest tip ..
Comment 3 Sven Gothel 2014-01-10 16:06:45 CET 
Tested 'TestAWTCardLayoutAnimatorStartStopBug532' on OSX 10.9 (CALayer) ..

Experience:

1- LABEL: Shows
2- Switch to GLCanvas
3- GLCanvas shows 
4- Switch to LABEL
5- LABEL Shows
6- Switch to GLCanvas
7- Nothing Shows  ** BUG **

Can you confirm that the above is the issue at hand ?

    Simplify JAWTComponentListener's HierarchyListener:
      - Don't interfere w/ Component's visibility anymore!
        This shall reduce sideeffects.
        Utilize 'isShowing' in each Component specialization, i.e. GLCanvas.
    
      - On SHOWING_CHANGED if a parent caused a change
        of the tracked components showing state,
        propagate it to the offscreen-layer!
    
      - Remove all other complicated states!
    
    GLCanvas, GLJPanel:
      - Instead of 'isVisible()' use 'showing state',
        since only the 'showing state' reflects 'true' visibility
        throughout the hierarchy.
    
      - Add HierarchyListener and track volatile showing state
        to be used instead of 'isVisible'.
        Using a cached showing state is more efficient
        than quering 'isShowing()' all the time!
    
    NewtCanvasAWT:
      - Use 'isShowing()' instead of 'isVisible(), see above
