Finding terminal size for remote debugging

Back a few months ago (March/April 2021 time frame) I used to use PUDB debugger, and it would fit itself to the size of my terminal window. Now I am finding it will only display 25 lines by 80 columns. I have tried different $TERM values, but it doesn't change what I get.

This is a remote connection (ssh to remote system). I have tried this in a "tmux" session as well as a regular ssh session under Gnome-terminal and xterm. Tested with $TERM unset, as well as xterm-256color, xterm, gnome, linux, and screen-256color (tmux automatically sets $TERM=screen).

I don't have a simplified script to sun as a test, so the only option I have to try this is a full Tempest testcase, and I have to just close the terminal window so that I don't have to wait for the full testcase to run.

I'm presuming pudb must have a preferred terminal type. I also uninstalled pudb along with it's dependencies and reinstalled.
