Agents Pane Text Preservation

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

In the Agents pane, the “cursor” jumps all over and randomly pastes and deletes content as I’m writing it. Sometimes text from other conversations travels across new agent pans if I havent submitted the messages. Text I not preserved.

Steps to Reproduce

Open an Agents Pane, start typing.

Expected Behavior

I would expect each agent pane to be able to write, draft and save its state even if I navigate away form it.

Operating System

MacOS

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, thanks for the detailed report with the version and steps. There are actually two known bugs in the new Agents pane Glass, both on our side.

  1. The caret jumps and text randomly gets inserted or deleted while typing.
  2. Drafts leak between panes and don’t persist when switching. Right now the draft is tied to one shared slot, but it should be stored separately per agent.

Both are reproducible and already being tracked, but I can’t share an exact ETA for a fix yet.

A couple things that can help right now:

  • Before you switch tabs or open New Agent, send the draft or copy it somewhere else so it doesn’t get lost or mixed up.
  • Avoid switching tabs quickly until the draft is sent.
  • You’re on Release Track: Nightly, which is the most unstable build, so regressions show up there first. If this is blocking your work, it may be worth switching to the Stable track for now Cursor Settings > the Updates tab. The composer is more stable there.

Once I have an update on the fix, I’ll reply in the thread. Let me know if the workaround doesn’t help.

Okay I will wait for a fix, and just write my drafts elsewhere for now.
