TL;DR

Cursor's latest version exhibits unexpected behavior where it resumes 'thinking' after a prompt has already been stopped by the user.
The extra thinking is triggered when the user kills a background terminal process that Cursor was managing to run a server.
The presenter is unsure if this is a bug or intentional, but considers it counterintuitive and flags it as a heads-up for other users.

Summary

This short clip highlights an unexpected behavior observed in the latest version of Cursor, the AI-powered code editor. The presenter notices that after manually stopping a prompt, Cursor continues to display additional 'thinking' output — triggered by the act of killing a background terminal process that was still running a server. Rather than silently terminating, Cursor appears to re-enter a reasoning state within the existing chat context, producing output the presenter did not expect or request. The presenter is uncertain whether this is a bug or an intentional design choice in the new version, but flags it as odd and counterintuitive behavior. The clip serves as a quick heads-up for developers using Cursor who may encounter the same issue, particularly when working with background terminal tasks and AI-managed server processes. No resolution or workaround is offered — this is purely an observational note about a quirk in Cursor's current behavior.

FAQ

Why does Cursor keep thinking after I stop the prompt?

According to this clip, the behavior appears to be triggered when a background terminal process managed by Cursor is killed. Stopping that process causes Cursor to re-enter a thinking state within the existing chat context, even though the user has already stopped the prompt. Whether this is a bug or intentional behavior in the latest version is unclear.
