What issue are you seeing?

A codex thread gets stuck infinitely thinking once you paste in a large image.

This only happens on 0.154.0, I rolled back to 0.153.4 and it works fine.

What steps can reproduce the bug?

Create a thread with a large image. (https://photos.app.goo.gl/DoqhpXBWFcLaACuw8)

What is the expected behavior?

It doesn't get stuck.

Additional information

As I mentioned, it worked perfectly well in the previous version.

This only happens on 0.154.0, I rolled back to 0.153.4 and it works fine.

This also happens on the desktop app, I tried both.

Start by reproducing the thread termination with a large image on Windows using Codex CLI 0.154.0, then inspect the image-handling and thread lifecycle entry points. The codex doctor --json output provides environment details, including the Windows platform and runtime warnings. Done means the thread remains usable after a large image is submitted and the regression is covered by a test.
