Thanks Chauncellor, the stack trace is very good actually. It shows compiz is blocked in the intel driver: intel_update_renderbuffers () from /usr/lib/x86_64-linux-gnu/dri/i965_dri.so
This is probably the fault of the intel graphics driver, unless... 1. compiz is passing it invalid data. Looks highly unlikely; or 2. compiz is spinning at 100% CPU overwhelming the driver.
