Codex Desktop: request_user_input option info tooltips do not appear on hover in Plan mode when zoom level is above 100%

Summary

In Codex Desktop, Plan mode questions created via request_user_input show an info icon next to each option, but hovering over the icon does not display the option description.

This makes the UI hard to use when the short option label is not enough to understand the tradeoff. In my case, I could not confidently select an option because the important explanatory text was only available behind the info icon.

UPDATE: It turns out the issue occurs when the zoom level is above 100%. As far as I can tell, the tooltip element does appear in the app's DOM, but it’s positioned outside the page boundaries, so we can never see it.

Environment

• App: Codex Desktop
• Platform: Windows x64
• Codex App version: 26.513.4821.0
• Comparison:
• VS Code: the option description/tooltip interaction works as expected.
• Terminal Codex: there is no hover UI involved, so this specific problem does not occur there.
• Codex Desktop: the descriptions appear to be hidden behind the info icon, but hover does not reveal them.

Steps to reproduce

1. Set the Codex Desktop zoom level above 100% using the Ctrl++ shortcut.
2. Use Codex Desktop in Plan mode.
3. Trigger a request_user_input question with multiple options where each option has a description.
4. Hover the info icon next to any option.

Expected behavior

The option description should appear as a tooltip/popover on hover and be visible.

Actual behavior

There is no visible tooltip when hovering the info icon. Apparently, it exists somewhere in the DOM, but outside the page's boundaries.

Impact

This can make Plan mode questions effectively unusable when the descriptions contain the information needed to choose between options. The issue is especially noticeable when option labels are concise but the real tradeoffs are in the hidden descriptions.

Related context

There are other open Desktop hover/tooltip issues, but I could not find one specifically for request_user_input option info icons in Plan mode.
