string '=2s' shows up in Footer on remote terminals

[rhuygen]

This is a report of some strange behaviour in a remote terminal (ssh session to a Linux machine). The video shows that when I press '?' to show the help widget on the right of the terminal [at 13s], the Footer disappears and shows a string '=2s'. When closing the help widget, the Footer doesn't restore, it only restores when I scroll again in the Records panel [at 22s]. The header seems to refresh. The problem does not occur in a local Terminal (on my macOS).

Could it be that I have to explicitly refresh the Footer?

I just checked and the same behaviour shows when running the textual showcase app and press 'b' to toggle the sidebar:

python -m textual.app

I have experienced this same exact behavior. On the local terminal it works as expected, but on a remote terminal (PuTTY in my case) this '=2s' string appears and the footer disappears until scrolling.

This is fixed in the CSS branch.

hi, Can you provide the SHA hash or information of the fixed commit? I can copy it to my local and use it in the 0.1.18 version @willmcgugan
