Mate: compiz emerald won't start automatically

[Manfred Lotz]

Running Fedora 23 I got a problem to get compiz up with Emerald after
startup.

I have:

% gsettings get org.mate.session.required-components windowmanager
'compiz-mate-emerald'

% gsettings get org.mate.Marco.general compositing-manager       :(
true


When loggin into Mate I end up without any window manager. After
starting compiz-mate-emerald all if fine.

Any idea what might be wrong?

Thanks.
