Cursor 3 Agents Window - Review view doesn't allow expaning file to see more lines more than once

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When reviewing changes in split view on the agents window, if you click the arrow to “show more lines”, it only expands once, you can not click it again to view more lines. clicking the button does nothing the second time.

Down or up arrows in the attached screenshot, next to “353 unmodified lines” are the buttons that have the issue.

Steps to Reproduce

  1. In agent window (Cursor 3), ask the agent to make a change to a file with at least a couple hundred lines
  2. Review the changes with split layout selected, in the agent window
  3. Try to expand the area shown around the change in either direction. It will expand once, but clicking it again to show more lines does nothing

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hi @DylanClemann!

I haven’t been able to reproduce this so far on 3.1.14 (shouldn’t have any changes since 3.1.10).

Could you run Ctrl + Shift + P > Toggle Developer Tools to see if there are any console errors when you try to expand to see more lines (and it fails to do so)?

Here’s a video showing the issue. Nothing pops up in dev console when clicking.

Hey @DylanClemann!

Thanks a lot for the follow-up. I can reproduce it now! I wasn’t using split view.

I’ve filed a bug with the team.
