What issue are you seeing?

I use tmux with 3 panes, top middle, bottom. Codex in bottom (others are logs etc). I switch between panes (CTRL-B up/down) and when I zoom pane Codex (CTRL-B z) codex shows old output/dialog, erasing latest. I have to manually ask Codex to repeat what it said. Going back to unzoom will not solve it.
