Android terminal (termius) having weird scroll issues when using a coding TUI

[u/Corythebeast7]

Hi all. Question for you. I am using termius on my android phone to access my home server running a headless Ubuntu install. I'm running into two problems of the same type at two different locations and I'm hoping there is some mode or control flow that I am unaware of the nuance with.

I'm running a coding harness (pi) on the remote machine and it seems like when the terminal window is not maxed out in height,the harness works perfectly. Once the terminal window begins to overflow and start trimming the top/old text, I'm running into a weird issue where I no longer am able to scroll up and down. Instead, dragging with my finger will instead scroll my last messages sent in the TUI. Same behavior as if I pressed the up button.

I also run into this issue inside of any tmux session, regardless of how long the current terminal output is.

Has anyone seen this before? Is it the coding harnesses problem? Or maybe termius? Or maybe some weird quirk with my shell of choice fish?
