Lightroom Classic panels missing from screenshots in Computer Use

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

26.903.71938

What subscription do you have?

Pro

What platform is your computer?

Darwin 24.6.0 arm64 arm

What issue are you seeing?

Observed:

• Computer Use initially returns complete Lightroom screenshots.
• After automated clicks, its screenshots omit the side panels, module picker, and filmstrip.
• The panels remain visible on the physical display, and an independent capture method still captures them while Computer Use screenshots are incomplete.

The missing panel regions appear black within the unchanged image dimensions; the photo remains visible.

What steps can reproduce the bug?

mcp__cua_repl.js:

1. Open Lightroom → Develop with panels visible.
2. Run let lr = await cua.getApp("com.adobe.LightroomClassicCC7");, then separately await lr.getScreenshot();. Confirm a complete screenshot.
3. Click somewhere and capture again:

await lr.click([350, 9], {mouseButton: "left"});
await lr.getScreenshot();

What is the expected behavior?

Expected: panels remain in the screenshot. Actual: panels are missing.

Additional information

Environment: ChatGPT Work 26.903.71938 (8576), Astra; runtime 0.153.4; Computer Use helper 26.902.1000968; Lightroom 15.4.1; macOS 15.7.9 (24G830), M4 Max.

Start by reproducing the issue with mcp__cua_repl.js using Lightroom Classic on macOS: capture the initial screenshot, perform the documented click, and capture again. Trace the Computer Use screenshot path and compare it with the independent capture while checking the side panels, module picker, and filmstrip. Done means post-click screenshots retain those regions without changing the existing reproduction behavior.
