On a new install of Ubuntu, two things seem invaluable; turning off
NetworkManager before doing anything else, and ensuring that automatic
upgrades are disabled. Stability is more conducive to sanity and
productivity than having the latest bugs, ISTM. (OK, an occasional
peek at the Update Manager, and acceptance of security upgrades, could
let in a new bug too, but I've been fortunate so far.)
Incidentally, to protect against unfortunate upgrades, I keep the older
OS version, installing the new version in another partition. If it isn't
much chop, it can be overwritten when a better one comes along. If it's
OK, then installs alternate between partitions, clobbering the older
version, as I upgrade once every 3 years or so.

Giving up Compiz for Metacity or other WM, temporarily, might confirm
that Compiz is the culprit. Then reversion to an older version ought to
fix it, with a bit of luck. (An "apt-get remove --purge compiz"
hopefully won't leave much of the current install, but e.g. with apache2
I've had to clean out leftover subordinate packages.)
