TTY rendering broken or disabled after latest update

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

(edit so this only applies to the new terminal the legacy teminal still works)

The latest update seems to have broken something with tty rendering in the terminal. My project uses turbos tui to switch between bundled applications. After the latest update the built in terminal falls back to stream rendering doesn’t render the tui correctly and becomes non interactable when trying to run the project. Trying to force the tui with specific commands does not work either. To confirm that this was a cursor specific issue and not a project setup one I was able to successfully run the project with the working tui in the default mac terminal and in the vs code terminal.

Steps to Reproduce

run a mono repo using turbos tui interface

Expected Behavior

the tui should render correctly like it was previously to this update

Operating System

MacOS

Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, thanks for the report. This looks like a regression in the new terminal in version 2.2.x, and we’re seeing similar issues from other users.

Since the legacy terminal works for you, I’d recommend using it as a temporary workaround for now.

For debugging, could you share:

• The Request ID right after trying to run turbo in the new terminal
• A screenshot or error output showing the fallback to stream rendering
• The exact command you’re running
• Logs from Help > Toggle Developer Tools > Console (after running turbo)

This will help the team understand what’s breaking in the TTY rendering.
