Title: High CPU Usage Causing Severe Freezes (Cursor Helper Plugin since v46)

After updating to Cursor v46, I’ve encountered severe performance degradation. Whenever I type or edit text, the editor freezes consistently for about 2-4 seconds. Cursor Tab model takes 4-5 seconds to comeup with a suggestion. The application has become practically unusable due to these frequent interruptions.

Upon checking Activity Monitor, I’ve identified a process named Cursor Helper (Plugin): extension-host [3-3] consuming over 100% CPU.

Steps to Reproduce:

  1. Open Cursor, 2-3 tabs, work at them simultaneously for a couple of hours
  2. Start typing or editing text in any file.
  3. Observe significant freezes of around 5-6 seconds frequently.

Operating System: macOS, MacbookPro M3 Pro, 36 gb RAM

Cursor Version: v46

Impact: This issue severely impacts productivity and usability, making Cursor nearly impossible to use for regular coding activities.

Hey, Cursor Helper (Plugin): extension-host [3-3] indicates that the issue is caused by extensions. Open the Process Explorer to try identifying these extensions.

hey that’s the screenshot with extension-host [3], I can’t see here any specific “extension” that makes it load under 100%

Do you have many extensions installed? Previously, users complained about an extension called Import Cost. If you have it installed, try disabling it. If not, I think you’ll need to disable all of them and enable them one by one to find the problematic extension.
