codex - 💡(How to fix) Fix Codex Desktop plugin marketplace layout is horizontally clipped on Intel Mac unless --force-device-scale-factor=1 is used

What version of Codex is running?

Codex Desktop App version: 26.506.21252

What platform is your computer?

macOS on Intel Mac (x86_64).

What issue are you seeing?

The Codex Desktop App plugin marketplace page renders incorrectly on my Intel Mac. The plugin list appears horizontally shifted/clipped: most plugin card content is cut off, with large blank/blurred areas and only the right side of plugin rows/buttons visible.

This happens consistently in the Plugins page. The plugin data appears to load, but the layout is miscomputed, so the page is hard to use.

Steps to reproduce

1. Open Codex Desktop App on an Intel Mac.
2. Go to the Plugins page.
3. Observe that plugin cards/list items are horizontally clipped or shifted, so only partial text/buttons are visible.

Expected behavior

The plugin marketplace/list should render normally, with plugin names, descriptions, and install/manage buttons visible and aligned.

Actual behavior

The list is horizontally offset/clipped. Only parts of the plugin rows are visible, and large blank/blurred areas cover the main list area.

Workaround found

Launching Codex with a forced device scale factor fixes the layout:

open -na /Applications/Codex.app --args --force-device-scale-factor=1

Direct launch also works:

/Applications/Codex.app/Contents/MacOS/Codex --force-device-scale-factor=1

Using the normal Dock/Finder launch reproduces the broken layout again.

Things already tried

• Reset app zoom with Cmd+0
• Refresh/relaunch Codex
• Restart the app
• Remove/rebuild main app caches under ~/Library/Application Support/Codex/
• Remove/rebuild the Partitions/codex-browser-app cache, code cache, GPU cache, session storage, local storage, shared storage, and blob storage
• Remove an older /Applications/Codex-intel.app install so only /Applications/Codex.app remains

None of those fixed it. Only --force-device-scale-factor=1 fixes the display.

Additional context

This looks like an Electron/Chromium HiDPI scaling or compositor/layout issue on Intel Mac. There are existing Intel Mac rendering-related issues such as #18341, but this one affects the Plugins marketplace/list page specifically.

I can provide screenshots if needed.
