After one of the latest updates I discover some new behavior for some applications (firefox, thunderbird, libreoffice (all of them), google-chrome. No matter how I start listed applications (from terminal, menu ...) they always maximized. As I found in Gnome 3.4 release notes, this is default options for all applications. But I found also that if I logout user from desktop environment (gnome-shell and cinnamon) with active applications in it, they are always restore previous window size after login. I wonder where gnome 3 saves application window's position and size?
