Cursor loses focus in chat input when in-editor browser is active

[StergiosDikos (Stergios)]

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

While typing in the Cursor AI chat text box, the input intermittently loses focus when the in-editor browser is active and running. The text box becomes deactivated mid-typing, requiring a mouse click to re-activate before continuing to write.

Steps to Reproduce

1.	Open Cursor AI
2.	Open or activate the in-editor browser panel
3.	Click into the chat text input
4.	Start typing continuously
5.	While typing, allow the agent to interact with the in-editor browser page (for example: reading the page, taking screenshots, or performing automated actions)
6.	Observe that the chat text input loses focus unexpectedly during typing

Expected Behavior

The chat text box should retain focus while typing, regardless of activity in the in-editor browser, unless the user explicitly clicks elsewhere or changes focus intentionally.

Operating System

Hey, thanks for the report.

This is a known issue, and the team is working on a fix. It seems to be caused by a focus management conflict between the built-in browser and the chat while the Agent is actively interacting with the browser.

I’ll add your topic to the existing issue so the team can include your case while working on the fix.
