Hey, thanks for the report. This memory leak with multiple agent chats has been reported by several users recently. Let’s run a quick set of diagnostics to narrow down the cause.
Quick diagnostic steps:
Test without extensions:
cursor --disable-extensions
Check if the memory issue still occurs.
Check Process Explorer: CMD+Shift+P → “Developer: Open Process Explorer”
Please share a screenshot showing which process is using the most memory.
Clean up globalStorage (this recently helped in a similar case):
• Completely close Cursor
• Press CMD+Shift+G in Finder
• Go to: ~/Library/Application Support/Cursor/User/globalStorage/
• Rename state.vscdb and state.vscdb.backup by appending something like .old
• Restart Cursor and check for updates (Help → Check for Updates)
Check for console errors:
Help → Toggle Developer Tools → Console tab → take a screenshot of any errors you see.
It would also be helpful to know:
Which extensions you have installed
Approximately how many messages you have in each agent chat
Same is happening to me, it’s using far more than 3GB just by stay opened without any file or tab. My setup also is very “minimal” talking about extensions
