Bugs in chat tabs with an agent

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

You’ve messed everything up with the latest updates.
Now, in the most recent chat, the model’s response to the latest message appears in a small font, whereas before it used to be large—a feature that distinguished it from older chats or messages.

While generation is in progress, there is no icon in the chat tabs to indicate that generation is happening, so it’s unclear where the process is taking place.

Once generation finishes, there is no icon on the chat tab to indicate that an operation has completed but hasn’t been viewed yet.

All of this makes things much more difficult.

Steps to Reproduce

create several chats and send requests to the agent in some of them

Operating System

Linux

Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

Hey, thanks for the detailed report. I’ll go point by point:

  1. Font size of the last reply. In the new chat UI 3.10 we removed the separate larger size for the last message. Finished turns are now grouped, so the rule “last message is larger” no longer exists. You can adjust the overall chat text size in settings chat text size.

  2. Generation indicator. While generating, the active tab shows a spinner so you can tell where it’s running.

  3. Status indicators. They’re there, just split by state:

  • An orange dot on the tab shows when the chat needs your input. Documented in the changelog: Chat tabs, Custom modes & Faster indexing · Cursor
  • In the sidebar, open chats show status: active ones have a spinner, and finished or unread ones have a blue dot. The chat needs to be open in a tab, not just in history.

Also, since version 1.5.x+ there are desktop notifications that fire when the agent finishes or needs confirmation at Settings > Sound Notifications / notifications.

If you want a clearer “done” marker like a checkmark or badge right on the tab, that’s an open request you can support: Show completion indicator on individual agent chat tabs

Let me know if anything behaves differently from what I described.
