Public bug reported:

Running the atom editor (www.atom.io) on ubuntu 14.04 with gnome-panel +
compiz leads to compiz crash when pressing alt-tab to switch to a
different window.

Reproduces every time.

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System
-> About Ubuntu

Description:	Ubuntu 14.04.5 LTS
Release:	14.04

2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center
compiz:

  Installed: 1:0.9.11.3+14.04.20160425-0ubuntu1
  Candidate: 1:0.9.11.3+14.04.20160425-0ubuntu1
  Version table:
 *** 1:0.9.11.3+14.04.20160425-0ubuntu1 0
        500 http://ie.archive.ubuntu.com/ubuntu/ trusty-updates/main amd64 Packages
        100 /var/lib/dpkg/status
     1:0.9.11+14.04.20140409-0ubuntu1 0

3) What you expected to happen

I expected ctrl-tab to switch me to a different window.

4) What happened instead

The environment freezes, despite mouse still moving. No application or
item in the windowing system responds and ultimately compiz crashes (~5
seconds later), leading up to black screen followed by a default
graphical login prompt.

This bug is fully reproducible in my environment and I'm eager to help
debug it.
