Public bug reported: I recently upgraded to Oneiric Ocelot beta1.
By default, I logged in to unity 3d interface. I use firefox version 8 (aurora). * I have two windows of firefox running (with around 190 tabs). * When I maximize or un-maximize my firefox windows, the window title bar disappears on one of the windows. * So, I have to use keyboard short cuts for minimize or maximize operations Also, I noticed that when this problem happens, my task switcher (alt- tab) works weirdly. If I go to firefox, evolution etc. on the task switcher, the window of that app does not come up. It remains in a minimized state on the side bar. The only way to recover from this problem is to quit/kill firefox and restart again, but the problem appears in a short while. Alternately, I have switched to Unity 2d and the problem is gone. This problem is not seen in chrome for eg. I saw some similar behaviour with evolution and other apps but I am not sure of what the exact behaviour was. $ lsb_release -rd Description: Ubuntu oneiric (development branch) Release: 11.10 $ apt-cache policy unity unity: Installed: 4.18.0-0ubuntu1 Candidate: 4.18.0-0ubuntu1 Version table: *** 4.18.0-0ubuntu1 0 500 http://us.archive.ubuntu.com/ubuntu/ oneiric/main amd64 Packages 100 /var/lib/dpkg/status $ apt-cache policy firefox firefox: Installed: 8.0~a2~hg20110923r75864-0ubuntu1~umd4 Candidate: 8.0~a2~hg20110923r75864-0ubuntu1~umd4 Version table: *** 8.0~a2~hg20110923r75864-0ubuntu1~umd4 0 500 http://ppa.launchpad.net/ubuntu-mozilla-daily/firefox-aurora/ubuntu/ oneiric/main amd64 Packages 100 /var/lib/dpkg/status 7.0+build2+nobinonly-0ubuntu4 0 500 http://us.archive.ubuntu.com/ubuntu/ oneiric/main amd64 Packages ** Affects: unity (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/861143 Title: unity 3d firefox window borders disappear To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/861143/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
