Pasted clipboard screenshots are not available to the agent when using WSL

What version of the Codex App are you using (From “About Codex” dialog)?

26.623.61825; also reproduced on every recent Codex App version/update I used during the last ~3 weeks

What subscription do you have?

ChatGPT Pro 5x

What platform is your computer?

Microsoft Windows NT 10.0.26100.0 x64; Windows with WSL2 workspace

What issue are you seeing?

When the Codex App is configured to work through WSL on Windows, screenshots pasted from the Windows clipboard are not available to the agent.

I take or copy a screenshot on Windows and paste it into Codex. From the user side, the paste action appears to work, but the Codex agent does not receive the screenshot as image context/attachment.

The agent behaves as if no image was provided.

There is no clear error message shown to the user. Text clipboard paste works normally. The problem appears to affect pasted screenshots/images when the active workspace is using WSL.

What steps can reproduce the bug?

1. Open Codex App on Windows.
2. Open or configure a project where Codex works through WSL.
3. Take a screenshot on Windows or copy an image to the Windows clipboard.
4. Paste the screenshot/image into Codex.
5. Ask the agent to inspect or describe the pasted screenshot.
6. The agent cannot see the image and responds as if no screenshot/image was provided.

As a workaround, I have to ask the agent to manually search for the screenshot in Windows temporary files through WSL-mounted paths, for example under /mnt/c/Users/.../AppData/Local/Temp/.... This workaround is unreliable and inconvenient.

What is the expected behavior?

When I paste a screenshot or image from the Windows clipboard into Codex, the agent should receive it as an image attachment/context.

This should work even when the active project/workspace is running through WSL.

Additional information

This has reproduced for me on all recent Codex App versions/updates I used during the last ~3 weeks, including version 26.623.61825.

The issue is specifically about pasted clipboard screenshots/images not being passed to the agent context when using a WSL workspace. The workaround of looking for temporary Windows screenshot files from inside WSL is not reliable and should not be necessary.
