### Where does the bug appear (feature/product)?

Cursor IDE

### Describe the Bug

I work under windows environment. When I ask the AI agent to produce some work for me, if I swith to another window to do other works, the cursor interface would freeze, and I have to close it through windows task manager. It’s very troublesome. You can see from the attached screeshot, the cursor disappears here.

### Steps to Reproduce

Just open the cursor, ask the agent to compose something, and while he’s working, switch to another window, the cursor IDE would freeze.

Hey, thanks for the report. This looks like a known bug. We’re tracking it here: [Cursor freezes on final “Review Changes” step in Agent Mode](https://forum.cursor.com/t/cursor-freezes-on-final-review-changes-step-in-agent-mode/144457)

We need to confirm details and collect diagnostics:

- Does the pattern match: it freezes if the Agent finishes while the Cursor window is not focused
- Request ID of the frozen chat: chat menu (top-right) \> Copy Request ID
- Console screenshot: Help \> Toggle Developer Tools \> Console at the moment of the freeze
- MCP: Settings \> search “MCP” - which servers are enabled. Try disabling all MCPs temporarily and restart
- Extensions: launch with `cursor --disable-extensions` and check
- Process Explorer: `CTRL+Shift+P` \> Developer: Open Process Explorer - which process is spiking
- Update to the latest version and check if the bug still reproduces

As a temporary workaround, try keeping the Cursor window focused when the Agent finishes a step. Let me know if this helps and please share the data above.
