Bug description:
  The following bug has high impact on all users using fglrx ATI drivers since a long time. For every user using this proprietary driver the window decorations will not update besides on window resize - which is very confusing, since it's hard to know which window is currently focused, or what the correct title of the window should be. This greatly impacts the Ubuntu user experience.

  [Development Fix]
  Since we are dealing with a driver problem (which has already been addressed and is being analyzed with ATI), we decided on at least a workaround for this problem. Since the bug is caused by changes to a Pixmap not being passed to the underlying GLXPixmap (which happens for certain sizes and only certain Pixmaps), we force the rebinding of the decorator pixmap on decoration damage events.
  This ensures that the underlying texture is modified when needed.
  In order to workaround this problem, the compiz package was modified. The fix is being proposed in version 1: An earlier version of the package has also been tested by users from a local PPA (ppa:sil2100/ppa), version 1:

  [Stable Fix]
  The stable version of the workaround has been already proposed as a distro patch for the latest compiz package (lp:compiz).

  [Test Case]
  To reproduce the bug, an Radeon graphics card is required, as well as using the proprietary fglrx driver:
  - Open any number of applications
  - Try switching focus between them
    -> Most (or even all) windows do not change their window decorations (title bar) to indicate which is currently focused
  - Open a terminal
  - Change the current directory
    -> The title bar remains unchanged, even though it should indicate the current working directory

  For more test-cases, see original bug-description below.

  [Regression Potential]
  The introduced workaround fix has no potential regression possibilities. On non-fglrx systems, there might be an really small, additional performance footprint - since the texture is being rebound when not really needed. But it has absolutely no impact on the user experience.

  Binary package hint: unity

  I previously reported this as
  https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/768860. Further
  investigation on my part suggests the issue is with unity-window-

  The title bar is not updated on non-maximized windows unless the
  decorator is forced to redraw the title bar--usually on losing focus.
  I have confirmed this with GNOME-Terminal, GIMP, Firefox, and Geeqie.

  To reproduce:
  GIMP: Open a file. Modify it. Unless you switched to the Toolbox window, the image name doesn't get a prepended "*" to indicate the file has changed. Save it with CTRL-S. The "*" will not disappear until the window loses focus.

  Firefox: Open sites on multiple tabs. Switch between tabs as often as
  you like. The title bar text will not change unless the window loses
  focus. Maximize the Firefox window. Switch between tabs. The global
  menu title bar text will now change with each tab.

  GNOME-Terminal: Open a terminal. Change directories. Notice that the
  directory shown in the title bar does not match what is reported by

  Geeqie: Go to a directory with images. The title bar should change to
  show the name of each image as its displayed. Now maximize the window.
  The "title bar" text changes as each image is selected.

  For further testing, I chmod'ed /usr/bin/unity-window-decorator and
  restarted compiz-decorator to force the use of gtk-window-decorator.
  All title bars behaved normally (although I lost the rest of the unity

  Personally, I find this bug to be a show-stopper. I've been using the
  Unity interface for a week and this is one of the two issues that
  would keep me using the "classic" GNOME interface instead of Unity.

  This may be a duplicate of
  https://bugs.launchpad.net/unity/+bug/768356 but I was unable to
  append any comments to that bug. That report was also specific to
  Firefox, which I think is a bit misleading since the issue affects all
  applications which provide feedback via the title bar.
