This bug affects me since doing a fresh install of 16.04. I tracked it down to the Unity Dash/Docker. Whenever I hover over the left side of the screen, click an app, and on the mouseout (when the docker animation starts to hide it again) compiz crashes, takes a second, and comes back with the "oops, something crashed" dialog or simply a flicker of my open windows.
My current workaround: I'm using Cairo-Dock (aka Glx-Dock, cairo-dock package) for the moment, using it's "Login with Cairo Dock" feature upon Ubuntu greeter asking me for login. No crashes of compiz since then. [Long rant for the interested] I had a hard time finding this one with many hours of reboots... doing a fresh install, assuming a hard drive failure, then faulty RAM, trying to circumvent compiz by running Ubuntu MATE first, then switching to gdm via Ubuntu GNOME. All until I found the root is actually the docker, not compiz! I assume that there's something wrong with the FX animation and my graphics card/driver. Or the combination of the Unity Dock + Compiz...
