I don't know what this means. I cannot reproduce this: I see GDB announcing SIGWINCH when Emacs runs under tmux and the screen dimensions are changed. I don't know what you meant by "maximized then unmaximized the screen", but what I did was to press 'C-b "' to split the screen in half, and then 'C-b !' to join the halves into a single screen; both times GDB announced SIGWINCH.
