Agents window goes blank after sending a prompt — no response rendered

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In the Cursor Agents window, after I send a prompt, the main content area stays completely blank. There is no user message, no agent reply, no loading indicator, and no error message.

The bottom input still shows “Send follow-up”, and action buttons like “Continue Working” and “Commit & Push” remain visible, as if a task finished. But the conversation/output pane never renders anything, so I cannot tell whether the agent ran, failed, or is stuck.

Steps to Reproduce

  1. Open Cursor IDE and go to the Agents window.
  2. Select model: Cursor Grok 4.5 High Fast.
  3. Set environment to This Mac.
  4. Send any prompt in the Agents window.
  5. Observe the main content area after submitting.

Expected Behavior

The Agents window should show the user message and the agent response (or at least a loading/thinking state while working). If the request fails, it should show a clear error instead of an empty panel.

Cursor Grok 4.5 High Fast

Additional Information

Urgency: High / Blocking

This issue is blocking my daily workflow. After submitting a prompt in the Agents window, the main panel stays blank with no response, loading state, or error. I cannot review agent output, continue the task reliably, or trust Commit & Push / Continue Working, because the UI looks finished while nothing is rendered.

Additional context:

  • Feature: Agents window (not regular Chat)
  • Model: Cursor Grok 4.5 High Fast
  • Environment: This Mac
  • OS: macOS (Darwin 24.6.0)
  • Observed UI state after submit:
    • Main content area completely empty
    • Input placeholder shows “Send follow-up”
    • “Continue Working” and “Commit & Push” buttons remain visible
  • Impact: Unable to use Agents for coding tasks until this is fixed or a workaround is provided

Please prioritize. Happy to provide more logs / screen recording if needed.

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey there,

This is a known client-side rendering bug, and it’s on our side, not your setup. The agent actually ran and its work is saved on our end. The conversation pane just failed to paint, so your prompt and the response are there, nothing is lost.

To get the content to show up:

  1. Fastest fix: Cmd+Shift+P, then Developer: Reload Window. This re-renders the conversation, and your messages and the response should appear.
  2. Or resize the window or panel, or scroll the transcript area a bit. That also forces a redraw.

Once it renders you’ll be able to review the full output before using Continue Working or Commit & Push.

Our team is actively working on fixes in this area, so it should get better in upcoming builds. One thing that would help us pin down your exact case: when the pane is blank, does hovering over it or resizing the window bring the content back on its own, or does it only come back after a full Reload Window? Let me know and I’ll flag it accordingly.
