Status changed to 'Confirmed' because the bug affects multiple users.

[Ursula Junque (ursinha)]

This happened to me today after dist-upgrading from precise to quantal. Once the machine returned from reboot, I logged in and hit this bug. I actually didn't run any commands for this to happen.

Fix committed into lp:compiz at revision 3389

[Launchpad Janitor (janitor)]

This bug was fixed in the package compiz - 1:0.9.8.4-0ubuntu1

---------------
compiz (1:0.9.8.4-0ubuntu1) quantal-proposed; urgency=low

  * debian/control:
    - Add dependency on gnome-settings-daemon for compiz-gnome, since some
      tests need the g-s-d gsetting schemas
  * New upstream release.
    - FTBFS with -DCOMPIZ_BUILD_TESTING=OFF if libgtest-dev is not installed
      (LP: #1057421)
    - [performance] glXSwapIntervalEXT called every frame, which is very slow
      on Nvidia. (LP: #1051286)
    - opacify plugin: opacity isn't reset after switching window (LP: #1050757)
    - cmake fails on python 2.6 as sys.version_info does not contain
      major_version or minor_version (LP: #1048964)
    - scale mode is not visible if a fullscreen window is unredirected
      (LP: #1047168)
    - Unredirected fullscreen windows flicker briefly when another window
      (like a menu) opens above them (LP: #1046664)
    - Week33 - Grid highlight window appears while switching between workspaces
      (LP: #1037142)
    - gtk-window-decorator leaks large numbers of pixmaps and pixmap memory
      (LP: #1057263)
    - [fglrx] compiz crashed with SIGSEGV in glXDestroyContext()
      [/usr/lib/fglrx/libGL.so.1] from GLScreen::~GLScreen() (LP: #1054724)
    - Maximized window gets unredirected when it's not fullscreen
      (LP: #1053902)
    - Double shortcuts conflict with gnome-control-center ones (LP: #1050796)
    - gtk-window-decorator leaking window handles. Window operations become
      sluggish after a few days of usage (LP: #1050610)
    - [valgrind] Up to 520,000 bytes lost when running
      CCSGSettingsBackendConceptTest (LP: #1049169)
    - 1:0.9.8+bzr3319-0ubuntu1 regression: keeps setting gsettings keys to
      wrong values (LP: #1042041)
    - Compiz r3275 breaks VirtualBox Guest Additions: black screen or just
      wallpaper (LP: #1030891)
    - Incorrect (low/stuttering) refresh rate with NVIDIA driver (LP: #92599)
    - ARM build broken with 'swapInterval' is not a member of 'GL'
      (LP: #1056645)
    - compiz.fix_927168 broke ARM building (LP: #1052838)
    - compiz crashed with SIGSEGV in __strcasestr_ia32() from
      ccsStringToModifiers(binding=NULL) (LP: #1041535)
  * Cherry-picked from upstream:
    - ABI bump due to an ABI change in the composite plugin
    - Removed schema keys still used in keybindings and automated tests
      (LP: #1057955)
