Images/screenshots fail to upload when chat is moved to a separate editor window -

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

When I detach a chat from the main sidebar and open it in a separate editor tab/window (editor view), attaching screenshots or images no longer works — uploads fail or never appear in the chat.

Steps to Reproduce

teps to reproduce:

Open a chat in Cursor.
Move/separate the chat into its own editor window (editor view, detached from the main panel).
Try to attach or paste a screenshot/image into that chat.
Image does not upload / attach successfully.
Expected: Images and screenshots upload the same way as in the main sidebar chat.

Actual: Images/screenshots do not upload when the chat is in a detached editor window.

Additional Information

Notes: Works normally when the chat stays in the main sidebar; only breaks after separating to editor view.

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hi @taha.b!

I can’t reproduce this.

  • Am I doing anything differently than you?
  • Can you share a Request ID from a chat where this didn’t work?
  • What does “breaking” look like? (Screenshots would be great!)
