Look at the photo again.  Notice at the bottom (which is actually the
left side of my screen) you'll see that the launcher is clearly visible,
yet beneath all the open windows.  Notice at the top (which is the right
side of my screen) you'll see the shutter window displaying the screen
cap I took using Shutter.

SO, what this is showing is that while Shutter thinks that the launcher
and app lens are on top of everything, they are actually below
everything.

That being said, I did forget to use apport-collect, so thanks for
reminding me...

** Description changed:

  Weird behaviour with Unity launcher.  I run a fair number of windows
  during the day, Chrome, a couple terminator sessions, IRC, mumble and so
  forth.  I usually maximize the chrome window and use the app switcher in
  compiz to swap between the other windows.  What I've found is that at
  some point after I've been running for a while, the Unity launcher stops
  appearing on top of everything.
  
  Instead, it appears under all windows.
  
  Unfortunately, the graphics system seems to think this is not the case.
  I tried several screenshots and every single one showed the launcher and
  the app lens on top of everything, even though to me, it appeared below
  everything.
  
  So, I'm attaching a photo taken with a digital camera.  If you look
  closely at the photo, you'll notice a couple of things.  First, there's
  a Shutter window open showing one of the screen caps that clearly shows
  the launcher and app lens on top.  BUT if you look just to the left,
  you'll see that in fact, the launcher is actually BEHIND the terminator
  window.
  
  Try as I might, every screencap shows the launcher as it SHOULD be, not
  as I actually see it.
