compiz (1:0.9.7.12-0ubuntu1) precise-proposed; urgency=low

  [ Łukasz 'sil2100' Zemczak ]
  * 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.

Bug description:
  [Test Case]
  1. Open CCSM
  2. Navigate to ccsm -> Composite
  3. Enable unredirect fullscreen windows
  4. Reboot
     -> Verify that after the reboot Unity works correctly

  [Regression Potential]
  Visual regressions at most.

  Original description:

  Setting "unredirect fullscreen windows" in ccsm prevents compiz to
  start on the next startup, the only visible part of the screen will be
  the wallpaper. The only way to recover is logging into Unity-2d and
  resetting the default compiz settings, where that option is disabled.

  To reproduce, simply:
      - navigate to ccsm -> Composite
      - enable unredirect fullscreen windows
      - reboot
