1) unity --replace also seems to reload compiz (will test this more)
2) disabling vertex buffer doesn't seem to do anything
3) got full trace, seems consistent across 100%cpus:

Title:
compiz 100% cpu on boot
Status in “compiz” package in Ubuntu:
New
Bug description:
Ubuntu: 14.04
Video card: 00:02.0 VGA compatible controller: Intel Corporation Mobile
945GSE Express Integrated Graphics Controller (rev 03)
CPU: dual core Intel(R) Atom(TM) CPU N270 @ 1.60GHz
compiz:
Installed: 1:0.9.11+14.04.20140423-0ubuntu1
Candidate: 1:0.9.11+14.04.20140423-0ubuntu1
xserver-xorg-video-intel:
Installed: 2:2.99.910-0ubuntu1
Candidate: 2:2.99.910-0ubuntu1
Monitors: 2
Display resolution: 1024x600, 1024x768, arranged top-bottom
When I boot up, I confirm that compiz is using up to 100%-"150%" cpu.
When I take monitor 2 off I notice compiz use drops but not to 0 -- it drops
to around 50% (still rather high compared to the ~10% it typically runs at)
running
compiz --replace
in a shell without environment variables triggers compiz to restart
without 100% cpu use allowing system to be usable
