Attachment data loss while queue is being processed

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When I have queues being processed for a chat prompt
and i am writing new prompts, with attachments
if i’m unlucky enough that a new queue entry starts processing
the attachments vanish

Steps to Reproduce

  1. Have a bunch of queue entries being processed (ongoing processing)
  2. start writing a new prompt, into the same chat tab
  3. drag a few images to the new prompt
  4. wait for one queue entry to finish and a new one to start processing
  5. the attachments in your “not yet put-to-queue” message vanish

Expected Behavior

the attachments in my not-yet-put-to-queue prompt should not vanish, resulting in me panicking and re-screenshotting and then writing panicked “write faster! or the attachments will get lost again” instructions, resulting in poor results.

Operating System

No - Cursor works, but with this issue

Hey, thanks for the report. This is a known issue with chat state management when processing the queue. The team is working on a fix for bugs like this.

As a temporary workaround, please wait until the current queue items finish processing before adding attachments to a new request.
