Comment 15 for bug 153458

I had this too, upgraded from Feisty to Gutsy and had the latest version of Compiz-Fusion.
First time and every subsequent time I started evolution, while running compiz, it lacked window decorations.
It worked fine when I did metacity --replace but not with compiz.
However turning off the "Legacy Fullscreen Support" option in the compiz workaround plugin fixed it using compizconfig-settings-manager
