What issue are you seeing?

Ever since updating to Codex CLI 0.131.0 or later, running codex inside the VS Code integrated terminal causes the TUI to fail to render. Instead, the terminal prints raw ANSI escape sequences, making Codex unusable. For example this is what I see in the output:

It works completely fine in version 0.130.0 or earlier.

I've tested it with versions 0.131.0, 0.132.0, and 0.133.0 (the latest release as of opening this issue) and they all have that bug.

In normal CMD or PowerShell, it works fine. But when running in the integrated vscode terminal it breaks (cmd and powershell). Using codex cli with WSL works fine within vscode still, so its something with Windows.

What steps can reproduce the bug?

1. Open VS Code.
2. Open the integrated terminal.
3. Install or switch to Codex CLI 0.131.0 or later (on Windows native, not WSL).
4. Run codex.
5. Observe that the TUI fails to render and raw ANSI escape sequences are printed instead.

What is the expected behavior?

It should display the TUI not raw ANSI escape sequences.

Additional information

This is what it looks like when running codex in the vscode cli: <img width="1263" height="1310" alt="Image" src="https://github.com/user-attachments/assets/0286e61a-5a16-4017-a4fb-d7f419148aba" />
