What issue are you seeing?

I'm using the Codex desktop app on Linux Mint 22.3 Zena, Xfce, running X11.

The Pet overlay opens normally and I can click the message input field. The text cursor appears and blinks as if the field is focused, but no keyboard input is received.

Letters, Backspace, arrow keys, Enter, etc. do not work.

Interestingly, pasting text into the field using the mouse works normally. This suggests that the text field itself is functional, but keyboard events are not reaching the Pet overlay.

Environment:

Linux Mint 22.3 Zena

Xfce

X11 (XDG_SESSION_TYPE=x11)

Codex desktop app downloaded from the official ChatGPT/OpenAI website on September 12, 2026

Steps to reproduce:

Open Codex.

Open the Pet overlay.

Click the Pet message input.

The caret starts blinking.

Try typing or using Backspace/arrow keys.

Nothing happens.

Paste text using the mouse — pasted text appears normally.

The keyboard works normally everywhere else, including the main Codex interface and other applications.

What steps can reproduce the bug?

nothing.

What is the expected behavior?

writing normally

Additional information

just this

Reproduce the failure in the Codex Pet overlay on Linux Mint with Xfce/X11, then compare keyboard handling there with the working main Codex interface. Trace the Pet overlay's input entry point and verify typing, Backspace, arrow keys, and Enter work while mouse paste remains functional; done means keyboard input works in the reported environment without regressing the main interface.
