I've downgraded the severity to normal, because compositing not working
doesn't prevent you to use xfwm.

Can you be more precise on the configuration you have (hardware and
software) ? Can you give xorg.conf relevant
informations, /var/log/Xorg.0.log.

I've opened a bug on Xfce bugzilla which you should follow
http://bugzilla.xfce.org/show_bug.cgi?id=2099 because it'll be there
where upstream will communicate.

Btw, Olivier, core xfwm developper, is in holidays, so I guess the bug
won't be treated until a week or so.

I can't really reproduce the bug because I don't use compositing on this
box (too slow, even with beta1). 

Are you sure that xorg or something wasn't upgraded when you upgraded to
beta2 too ?
