Chat UI shows internal comment-menu strings instead of AI response when attaching PDF/DOCX and asking about document comments

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

OS: Linux (Fedora)
What happened: After attaching 1 PDF + 2 DOCX and asking the agent to read comments in the documents, a popup appeared with internal UI copy like “The contributed comment thread title’s peek context menu…” instead of a normal chat response. Looks like Cursor’s code-comment UI strings leaked into the chat surface.

Steps to Reproduce

  1. In agent mode
  2. multitask selected
  3. Dragged and dropped 2 docx and 1 pdf into the chat (all have comments in them mad in google workspace tooling)
  4. ask for the agent to summarize in chat what the docs are about and how many comments are in the docs. and who made the comments

Expected Behavior

Expected: Agent reads attachments / answers about document comments.
Actual: Internal comment-menu descriptions + Request ID shown in a dialog.

Hey @Mikael_Sundh!

Thanks for sharing. That’s the first time I’ve seen behavior like that!

We had some issues with Grok 4.5 this morning, and I can’t find your Request ID in our backend, which makes me wonder if the request ever made it to our servers at all.

A few questions to help us dig in:

  • Does the issue persist in a new chat?
  • Is it always triggered by having a PDF plus multiple .docx files in a multitask chat? (I tried to reproduce this but wasn’t successful.)
  • Have you seen it come up in any other situations?

  1. you are on to something here. I tried it now and it does not persist in a new chat. I now get the correct output: full comments and source of comment report given accuratly
  2. I am not able to reproduce it now either.
  3. Nope, only this one time this morning. (I have never asked it to do a summary of the comments in documents before.

So it seems like it was some temporary hiccup.
I will be back if it happens again :).
