What issue are you seeing?

When attempting to paste text into Codex CLI, the following error message is displayed:

"Failed to paste image: no image on clipboard: The clipboard contents were not available in the requested format or the clipboard is empty."

Immediately afterward, without modifying the clipboard, I pasted the exact same content into a different terminal window, and it worked without any issues.

This suggests the clipboard contents are valid, but Codex CLI is incorrectly detecting the clipboard as containing an image or as being empty in that particular terminal instance.

What steps can reproduce the bug?

Uploaded thread: 019faef7-46c4-7a63-b1bb-c07850700636

What is the expected behavior?

Paste the text right away.
