Issue affects Mint Maya MATE and Mint Maya XFCE
Firstly, Compiz doesn't run on start-up even when on start-up list, just leaves an icon on tool bar you must click to activate it. Even when you do, Compiz effects don't immediately kick in but you must go into its window manager and -- even though it's "on button" is on you have to click it again to kick start it to go. When you do so, 1. you immediately lose all window control buttons. 2. all running apps if they were on different screens as via Window Switcher -- slam into one window and all Window Switcher app panels are wiped out. Also apps cannot be dragged around the screen. A reboot does not solve the problem, nor does compiz --replace.
Compiz is a good program and feature, but it cripples its usefulness by denying you button bars and messing with panel toolbar. If XFCE performed opacity for active windows you're working on I'd regrettably pass on Compiz. I'd be happy to help beta-test Compiz for a solution if I knew where!
