Hey, thanks for the report. To figure out what’s causing the severe lag, please share:

  • Test without extensions: run cursor --disable-extensions from the command line and let me know if the lag persists
  • Process info: CMD+Shift+P > “Developer: Open Process Explorer” - tell me which processes are using high CPU/memory
  • Extension Monitor: enable in Settings > Application > Experimental > “Extension Monitor Enabled”, then check CMD+Shift+P > “Developer: Open Extension Monitor” to see if any extensions are causing issues
  • Indexing status: check if codebase indexing is running in the bottom-right corner

Also, does the lag happen:

  • During typing?
  • When opening files?
  • All the time, even with no file open?
  • Only in specific projects/file types?

This will help determine whether the cause is an extension, indexing, or another process.
