After more research, this turns out to be a bizarre interaction of various things. The culprit is the intersection of this version of compiz and running older kernel versions. As soon as we updated to linux-image-3.13.0-49-generic, the problem went away. So I think it's still the case that some

It's weird that the Compiz update would cause this. The only changes in the last Compiz SRU are a blacklist for Nvidia cards for disable X to GL syncs and the removal of a texturesCache in the animation plugin that caused issues on Nvidia cards and that's it. The texturesCache was unused and only

Unfortunately we disable apport on our public workstations. I will try to reproduce it on a workstation with apport enabled and retrieve a crash file, if there is one. We do not use fglrx; we use the stock radeon (this is on 14.04.2, without the HWE stack), and the problem occurs on machines with

You can try looking in /var/carsh and see if there is a compiz related crash in there. Also, could you post the relevant lines in your syslog? Sometimes, compiz segfaults due to buggy drivers as well. Was there any update to your graphics driver? Are you using fglrx or radeon for your graphics
