I also have this problem. When I log in, most of the time the borders are there and it's fine. The problem often occurs when dragging a window from fullscreen on one monitor to fullscren on another. I click up in the upper unity task bar, where the menu goes when a window is fullscreen. I drag it down, and then up into the task bar on my other monitor. Once it goes fullscreen, I lose my window borders and menus for all my other open programs.
I can run compiz --replace to fix it, but I'm doing this a few times a day. ** Also affects: unity 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/780145 Title: Window title bar and borders dissapear in Ubuntu 11.04 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
