If you start gdb without -tui, and press ^Xo, it will switch to tui mode. I don't know if they've "fixed" this in newer versions, but I've found it useful.

That key sequence is emacs for switch to other window. If you're an emacs user but use gdb in the console it's the kind of thing you'll discover by accident sooner or later.
