I have deleted the package in the ppa as I can also confirm the issue as described by Franck. (previously I did not had access to Natty).
If you installed from the ppa and are facing the start-up problem then login to classic desktop, disable my ppa in software-sources and run the following command in terminal. sudo apt-get install compiz/natty compiz-core/natty compiz-gnome/natty compiz-plugins/natty libdecoration0/natty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/772612 Title: maximized window is displaced To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/772612/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
