11.10 - Changes in compiz don't affect Unity

I've just installed Ubuntu 11.10, and added Compiz (which wasn't there by default).

I've noticed, that all changes I make in Unity Plugin (launchpad behavior, icos size, transparency) don't affect Unity at all - it is just as it was after being installed.

The changes are stored (when I open the settings again all my changes are set), they just don't appear on the screen :)

Is there a way to solve this problem?
