Cursor Helper (Rendered) CPU explodes, and then there is a crash

I’m on the latest version of Cursor, and the window rendered is exploding the M4 MacBook Pro CPU use, up to 300%. I’ve been using Cursor for a while, and this is the first time that happened.

I checked the process explorer, and it’s not a plugin or anything, it’s the window. Eventually I get a crash that says:

The window terminated unexpectedly (reason: ‘crashed’, code: ‘5’)

Fortunately I’m able to reopen my windows and things like the terminal process are still running. But it’s fairly disconcerting.

Would you mind to post actual information that helps the Cursor team debug your issue? Its unclear what the purpose of your post is.

Let me know what information you need.

(Weird thing to say “post actual information” when I’ve included the specific process that is causing the crash, the error message and error code, and information about my machine, etc.)

I’m getting crashes, and I would like to not be getting crashes. (Also so weird to say, the purpose of your post. This is clearly a bug report. Oh well)

There is a Documentation button on top right here in the forum. It has a page about issue reporting.

probably you would like following link
https://docs.cursor.com/troubleshooting/troubleshooting-guide

Matthew, please have a look at the link i posted. it explains what additional info the Cursor Team would need to help you.

Hey, could you provide a screenshot from the Activity Monitor?

Here you go


And from Cursor’s process inspector

I see high CPU usage (435%) in the file test_openai.py and significant memory consumption (3146 MB). What is your project about? Maybe you’re using a lot of background requests, especially if it’s related to LLM.

That’s probably all it was. Though I could’ve sworn I was getting window closures even when the script wasn’t active at all. But now they haven’t come back since the morning, so I’ll be on the lookout and provide more info as it becomes available.
