Audacious bug in window manager in Ubuntu since 11.04 / 11.10

First of all, i thought its a bug in audacious, but when i mailed with devs from Audacious, they said its a BUG in Ubuntu window manager, which is Compiz..and its up there since Ubuntu 11.04 or 11.10.

what its all about?

its annoying bug, when u use audacious in a " winamp " view, and u have opened player with playlist, and when u want to minimize audacious, PLAYLIST is stayin avalaible on dekstop, when it also should get minimized to launcher.

Can anybody fix this bug in compiz??
