As commented on the mailing list, resetting compiz (dconf reset /org/compiz) & then logging into metacity does solve the problem. But it reappears when I log back in compiz session. Running "compiz -replace" inside metacity session also works-> It brings back all compiz effect & doesn't affect indicator-applet-appmenu.
I think Unity's compiz plugin in someway interfering with flashback-compiz session ( compiz has tons of bugs on Utopic).
