Please, is there a quick fix for UI freezes and lag issues in Cursor?

How To
1

I need help with a quick fix for Cursor’s lag issue. I’m using a Debian based distro.

Check your extensions, also check if any big file is included in Chat, that crashes it too

Yeah those are good suggestions! A few other things you can try:

  • Run cursor --disable-extensions to check if it’s extension related
  • Use Process Explorer (Command Palette > “Developer: Open Process Explorer”) to spot resource-heavy processes
  • Enable HTTP/1.1 fallback in settings if you’re behind a VPN/proxy
  • Check if you have enough disk space free

More details on performance troubleshooting here: Cursor – Common Issues

For Debian specifically, make sure you’re running the latest version and your system is up to date with sudo apt update && sudo apt upgrade

It crashes so badly I could barely visit the settings page
