"Unredirect Fullscreen Windows" stay on top (unredirected) even when an RGBA window is stacked above it

[Daniel van Vugt]

[Test Case]

1. Open a Chrome/Chromium window.
2. Open a gnome-terminal window (Ctrl+Alt+T)
3. Move the gnome-terminal to the centre of the screen, above the Chrome window.
4. Click on the Chrome window and make it fullscreen (F11).
5. Alt+Tab to the gnome-terminal window.
   -> gnome-terminal window should be visible on top

[Regression Potential]

Original description:

"Unredirect Fullscreen Windows" stay on top (unredirected) even when an RGBA window is stacked above it. This is an edge-case I missed in the general bug 1041047.

Test case:

1. Open a Chrome/Chromium window.
2. Open a gnome-terminal window (Ctrl+Alt+T)
3. Move the gnome-terminal to the centre of the screen, above the Chrome window.
4. Click on the Chrome window and make it fullscreen (F11).
5. Alt+Tab to the gnome-terminal window.

Expected: gnome-terminal window should be visible on top.
Observed: I can only see the Chrome window still. But right clicking in the middle of the screen makes the gnome-terminal window visible.

This bug was fixed in the package compiz - 1:0.9.8.2+bzr3377-0ubuntu1

---------------
compiz (1:0.9.8.2+bzr3377-0ubuntu1) quantal-proposed; urgency=low

  [ Sam Spilsbury ]
  * debian/python-compizconfig.install
    - Install compizconfig-python.pc
  * debian/patches/100_expo_layout.patch
    - re-add the expo layout that used to be in precise (LP: #1047067)
    - add some testcases

  [ Timo Jyrinki ]
  * New upstream snapshot.
    - Fix multiple window placement bugs (LP: #974242) (LP: #976032)
    - Don't waste CPU looping through and looking at all the windows if you're
      rendering an output that has no damage on it. (LP: #1014986)
    - Updated convert files to fix some typos in the key names. (LP: #1041631)
    - Fix crash when imgsvg is loaded, due to missing symbol
      (decor_apply_gravity from libdecoration). (LP: #956986)
    - Treat unresolved symbols at link time as an error, rather than letting
      them through and cause strange crashes later. (LP: #1043143)
    - Refactors a little bit of the upgrade code and gets it under test to
      prepare to fix (LP: #1042537)
    - Updated AUTHORS from the full bzr log, and re-sort the list.
      (LP: #1042095)
    - Fixes FTBFS for kde4-window-decorator (LP: #1041310)
    - Fix obvious omissions from the introduction of unminimize_*,
      which were causing the unminimize animation settings to be ignored
      (LP: #1040455)
    - resize plugin: don't crash if resize wasn't initiated externally
      (LP: #1045191)
    - Clean up capitalization (LP: #1045652)
    - Avoid division by zero, if plugins try to deform a window down to size
      zero. (LP: #1045235)
    - Make "Unredirect Fullscreen Windows" more reliable. This fixes the
      problem with unredirection failing to engage at all (LP: #1041066) when
      gtk-window-decorator creates offscreen windows that are stacked on top.
      This also fixes the problem with unredirect hiding all windows,
      because it thinks the desktop window should be stacked on top
      (LP: #980663).
    - Ensure unredirected windows don't stay unredirected if they're no longer
      on top. (LP: #1041047)
    - Fix launching terminal functionality and make show-hud default key
      visible. Update the defaults to org.compiz.integrated to reflect the
      actual gnome values pre-gnome-3. (LP: #1040081) (LP: #1046199)
      (LP: #1046190)
    - Fix show-hud, bump COMPIZ_GNOME_INTEGRATED_SETTINGS_LIST_SIZE.
      (LP: #1046212)
    - Fixed: Windows with an alpha-channel, like gnome-terminal, were not
      being considered as possibly covering fullscreen windows. But they most
      certainly can. This ensures such RGBA windows are visible if they're
      stacked above a fullscreen window. (LP: #1046661)
    - Remove ListToStringList (LP: #1046184)
    - Fix typo causing CMake Error (LP: #1045665)
    - Transitions gtk-window-decorator over to use GSettings. Add a testing
      framework for the options code. (LP: #1042323)
    - Also need kdeworkspace since kdecorationbridge.h is there
      (LP: #1046770)
    - Implements some cleanup that was suggested on the merge for the original
      port to gsettings. Other issues fixed as wel...
