F8 clearing the name is a feature of Byobu. ctrl-a-A is screen's hotkey, and if you use it, you get whatever screen does with that keybinding. In your case, it allows you to change the name of the window, without clearing it.
This isn't a bug in Byobu. You could perhaps ask screen to change this behavior, but I doubt they would. ** Changed in: byobu (Ubuntu) Status: New => Invalid -- Rename window using screen-escape key bindings https://bugs.launchpad.net/bugs/485398 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
