"Unredirect Fullscreen Windows" stay on top (unredirected) even when they're not on top any more (or the output is transformed)

[Daniel van Vugt]

[Test Case]

1. Open Chrome/Chromium and go full screen.
2. Right click on the web page.
   -> Context menu visible

[Regression Potential]

Problems with unredirected fullscreen windows.

Original description:

Using Unredirect Fullscreen Windows mostly seems to work for me. However sometimes I find that opening a transient window above the unredirected fullscreen window fails:

Testcase A:
1. Open Chrome/Chromium and go full screen.
2. Right click on the web page.
Expected: Context menu visible
Observed: No context menu visible (yet my debug output tells me that compiz knows the fullscreen window is no longer on top and should be redirected).

Testcase B:
1. Open a video on mplayer
2. Hit F to go fullscreen.
3. Hit Alt+Space to open the window menu
Expected: the window menu should open in the top-left corner of the screen
Observed: No window menu opens (yet my debug output tells me that compiz knows the fullscreen window is no longer on top and should be redirected).

Testcase C:
1. Start playing a video full screen.
2. Trigger expo mode.
3. Leave expo mode (return to the full screen video)
4. Trigger expo mode.
Expected: Expo mode works each time it's triggered
Observed: Expo mode is not visible the second time. The unredirected fullscreen window stays on top.

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...

[Adam Conrad (adconrad)]

Hello Daniel, or anyone else affected,

Accepted compiz into precise-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/compiz/1:0.9.7.12-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

[Timo Jyrinki (timo-jyrinki)]

With the precise-proposed update, context menu continues to open fine in Chromium's full screen mode.

[Colin Watson (cjwatson)]

The verification of this Stable Release Update has completed successfully and the package has now been released to -updates.

  * debian/patches/revert_fix_994841.patch,
    debian/patches/revert_fix_933776_955035.patch
    - Removed, upstreamed
  * debian/watch:
    - Changed to the correct LP tarball path
  * debian/patches/compiz-package-gles2.patch:
    - Updated GLES patches to properly apply to the new compiz version

  [ Timo Jyrinki ]
  * New upstream release.
    - Compiz won't start if "unredirect fullscreen windows" is enabled
      (LP: #980663)
    - "Unredirect Fullscreen Windows" stay on top (unredirected) even
      when they're not on top any more (or the output is transformed)
      (LP: #1041047)
    - Unredirect Fullscreen Windows sometimes fails to unredirect fullscreen
      windows at all (LP: #1041066)
    - "Unredirect Fullscreen Windows" stay on top (unredirected) even when
      an RGBA window is stacked above it (LP: #1046661)
    - scale mode is not visible if a fullscreen window is unredirected
      (LP: #1047168)
    - Unredirecting a fullscreen window on a secondary monitor causes that
      monitor to flicker (LP: #1050749)
    - "Unredirect Fullscreen Windows" makes multi-monitor rendering much
      slower (LP: #1051885)
    - [regression] Maximized window gets unredirected when it's not
      fullscreen (LP: #1053902)
    - Unredirected fullscreen windows freeze and stay on top when wall
      sliding (Ctrl+Alt+Left/Right) (LP: #1084401)
    - "Unredirect Fullscreen Windows" can cause significant tearing on
      fullscreen windows (especially playing video) on some drivers
      (LP: #1051802)
    - HTML5 video in Firefox continues to tear (LP: #1086337)
    - Add support for blacklisting some drivers from using unredirected
      fullscreen windows. By default intel and nouveau on Mesa 8.0
      are blacklisted, configurable via ccsm. Users can upgrade to
      Mesa 9.0 around 12.04.2 time. (LP: #1089246)
    - Unredirect fullscreen windows should be the default for optimal
      performance (LP: #1063690)
  * debian/patches/workaround_broken_drivers.patch:
    - Updated to apply.
  * debian/patches/force_unredirect_enabling.patch:
    - Enable unredirect_fullscreen_windows unconditionally. Because of
      gconf hurdles we can't easily migrate existing users into the
      new default otherwise. Unredirection can be easily disabled with
      the new unredirect_match option, by blanking it completely,
      including removing the '(any)' part.
  * debian/patches/compiz-package-gles2.patch:
    - Update for the new blacklisting feature as well
  * debian/patches/blacklist_no_xml_double_escaping.patch:
    - Cherry-pick fix for the default string (LP: #1091103)

  [ Michael Terry ]
  * debian/patches/blacklist_no_xml_double_escaping.patch:
    - Update to also blacklist Mesa 9.0, which precise users may have from
      the x-updates PPA. 9.0 seems to have similar problems as 8.0 on
      Intel hardware.
