Hello, since I started using CODEX (several months ago now), there has been a significant terminal bug that can cause many users to make mistakes when operating the terminal. The bug in question is the “context window” remaining “left”, which is shown here:

<img width="615" height="150" alt="Image" src="https://github.com/user-attachments/assets/68aad5c0-2fe7-45b0-8ace-801ffbd44dd4" />

This context window always changes value while the agent is running, it is never reliable and I don't know why it hasn't been fixed for months now.

The second issue I encounter is the inability to scroll up the terminal when the agent is active. On other CLIs, this is possible, but on CODEX, it is still not possible, so most of the time, I am unable to check the modified code because it does not allow me to scroll up the terminal interface.

What steps can reproduce the bug?

Just when running the agents, for both issue

What is the expected behavior?
