Buggy performance after latest update

Hey, thanks for the report. This is a known issue after the latest update, and the team is aware. It looks very similar to Cursor is not usable after the last update

A few things to try:

Quick fix (if you need to work right now):

Workarounds that helped other users:

  • Clean reinstall
  • Start with cursor --disable-extensions. If that helps, it’s likely an extension issue
  • If you use MCP tools, try disabling them temporarily

Info needed for debugging:

  • What Cursor version are you on?
  • If you run without extensions, does the issue still happen?

Let me know what worked, or if nothing helps.
