Proprietary driver is a little complex to install due to dual Video Card. And I don't think the key point is nouveau because marco/metacity3.14/compiz don't have window missing issue.
As for current metacity 3.18.4-0ubuntu0.1, window title shadow unerased when switching Tab-page still exists (#46), though it is not a serious problem. And non-alphabet title displayment problem(#67) has been fixed! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1538111 Title: untraceable serious bug in metacity 3.18 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/metacity/+bug/1538111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
