Frequent Freezes in Cursor AI IDE - Any Solutions?

Bug Reports
1

Hi everyone,

I’ve been experiencing frequent issues with the Cursor AI IDE. The application tends to freeze every 1-2 hours, and I have to restart it to get back to work. This has become quite annoying, especially when I’m in the middle of coding sessions.

In the Activity Monitor, I notice a lot of tasks related to Cursor AI, which makes me think the problem might be tied to the application’s process management. My computer is fairly powerful, so I don’t suspect it’s a hardware issue on my end.

Has anyone else encountered this problem? If so, have you found any solutions or workarounds to prevent these freezes from happening? I’ve attached a screenshot from my Activity Monitor for reference.

Thanks for your help!

I have the same issue. I’m using an M3 MacBook Pro with 36GB RAM, so hardware shouldn’t be an issue. The codebase I’m working with is quite large; perhaps that could contribute to the problem? I have to restart very frequently.

Hello,

Information from the following may assist in further troubleshooting.

Copy/paste system info from:

Cursor > Help > About

Check for any relevant logs or errors in the following locations:

Open developer tools via:

Cursor > Help > Toggle Developer Tools

and then click Console and see if there are any related errors.

Also see the parent folder of the folder that is opened when doing:

  • Ctrl + Shift + P (to open command palette in Cursor)

  • Typing and selecting Developer: Open Logs Folder

You can also view logs in Cursor > Terminal > Output and then click on the dropdown and select Window or one of the other Cursor specific options, such as Cursor Tab or Cursor Indexing & Retrieval.

@litecode really annoying. Can’t work with comfort even though I paid for premium

I realized that one of my VSCode extensions was causing the lag. I deleted the extensions one by one, narrowed it down, and now it works well!

i had same issue and realized i had some extensions making api calls that worked same with cursor commands using commands like cmd+i and made api request after hitting the send key so somehow things were never resolved so i removed the extension and now it works.

Same thing here, using an M3 Macbook Pro and cursor is frequently super slow, freezes and crashes all the time. If this isn’t fixed I’m definitely ending my premium subscription this month. The codebase is somewhat large but really shouldn’t be an issue

Hey, can you try some of the steps in our guide here, which should help with any performance issues you are seeing: Cursor – Common Issues

I found a workaround for this that I often use in ChatGPT: simply start a new chat to stop the freezes.

This issue often occurs when you have a long chat history. It seems that the AI needs to quickly process the entire conversation each time before responding to a new prompt. When the history gets too long, it takes longer for the model to process, and the more advanced the model, the longer it takes—sometimes causing it to time out.

If this works similarly to ChatGPT, there may come a point when opening a new chat no longer fixes the problem. In that case, you would need to delete older chats to free up memory.

11

thanks a lot @tico you really helped with that info much appreciated and also yes it was freezing and quitting the whole app and I tried everything until I tried deleting old chats and its much faster now… anyone having problems with cursor lagging and freezing simply delete old chats and it’ll be much faster…

I have the same problem, literally all day every day, typing is impossible, it takes up to 30 seconds in best case, for the IDE to even respond. The fact that this is a production product is absolute proof that we live in an ideocracy. Also the IDE terminates about 30 times in an average day.

13

@tico how do I delete older chats to free memory? Literally every time I open cursor, I’m greeted with an “App not responding” pop-up. And this is only happening with 1 repository. Others work fine.

14

Just click on the clock icon to open your chat history. Then, hover over any of the chats to see the recycle bin icon appear on the right—that’s the delete button.

I’ve attached a screenshot to show you where the chat history icon is located.

this is the screen I get when I open the repository. Is there any other way to delete the chats than the UI? Also, I’m not sure if the long chats are causing this.

This is so ■■■■■■■ annoying I literally cannot open my projects. Editor just freezes. Not enough time to delete chats or anything.

17

I’d recommend uninstalling and reinstalling the app. Your chats have probably accumulated over time. I’ve found it helpful to delete them periodically—it tends to keep things running smoothly.

18

Just like me, when I open the source control, the entire IDE lags. I can’t click anything and it’s about to freeze after a few seconds.
vscode and windsuft is fine for this case.

19

@waltershewmake change the repo name, and reopen the renamed directory. It resets the long chats and stops the freezes. Atleast that helped me. Obviously not a clean solution, but it works, and you can keep using the IDE till you decide to cancel the subscription :face_with_tongue:
