I am using bash and GNU screen on centos7. I notice that if I ssh to another server, change the title (via ctrl+a+A), and log out of the server that my new title gets overwritten by USER@HOST:~. How can I stop it from doing this?

I've looked into dynamic titles and determined that's what's at play, but I'm unsure of how to disable that feature...

As documented in the man page, screen looks for a null title-escape-sequence. bash sends this sequence via the PROMPT_COMMAND environment variable (for example, mine defaults to printf "\033k%s@%s:%s\033\\" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}".

To disable this feature for a particular window, I just run unset PROMPT_COMMAND from that window. Of course, one could just add this to their ~/.bashrc or to a specific environment file to make it more persistent.

    If $PROMPT_COMMAND is empty, check $PS1.

On the screen mailing list, Steve Ross wrote:

I just realized that, although one approach is to unset the PROMPT_COMMAND variable, another approach is to use the "screen" command of "defdynamictitle off" in my "~/.screenrc" file. With this setting, the content of the PROMPT_COMMAND variable does not have an effect when opening new screen-window. For a previously opened screen-window, the related "screen" command of "dynamictitle off" lets you to turn off dynamic changes to the title of the screen-window.
