Older versions of compiz .debs can be downloaded from launchpad via package history:
https://launchpad.net/ubuntu/+source/compiz/+publishinghistory
Click on the desired version there on the right, and snag the appropriate .debs for your HW from under Builds at lower right.
However I suspect to downgrade compiz you may need to downgrade a few other things as well.
