We’ve noticed that users who always add messages to the same thread have had more performance issues compared to users who occasionally create new chat/composer threads. Can you share how often you create new threads?

Happy to also hop on a call and try to debug with anyone who has been getting the crash issues repeatedly, we’re not able to reproduce the crashes locally and are trying to hunt them down and fix them. Please DM me if you’re open to hopping on a quick google meet to debug.

thanks for offering that. I had emailed the support and sent them a loom video. It’s definitely an issue with the latest version as the prompt gets sent with a delay usually around 30 seconds. That’s just the prompt!
I wasted several hours and installed the previous version and that seems to fix the issue

Could you please tell me how did you installed the previous version? I am also experiencing the slowness and definitely because of the version 46.7. It is unbearably slow. I wanna go back to previous one. I would appreciate your help.

I have the same problem ā€˜oom’, code ā€˜-536870904’ can you help me ?

I went to the downloads page and downloaded the 0.45.x version. In my case the problems were on Mac so I used the universal version. The prompts are sent normally.

On Mac I replaced the version that I had previously installed.

Interesting. I tend to use the same thread. I will try creating a new one

im getting to a point where i cant even create a new chat thread without it crashing on me (admittingly never thought to create new chats as i went).

would be open to debugging if it would help you out (new account on here so cant dm yet i think)

Same here. It is extremely laggy

I guess the team was rushing the agent feature … but still every single one in the company should test the sh** out of this otherwise we’d lose the productivity we gain from the tool

Just sent you a DM, let me know if you can’t see it.

For others seeing these issues, clearing the local state might fix it.

In Windows, this is:
ā€œC:\Users\USERNAME\AppData\Roaming\Cursor\Userā€
And on Mac, this is:
ā€œ/Users/USERNAME/Library/Application Support/Cursor/Userā€

I’d recommending renamint the User folder to UserBackup or storing it somewhere in case you want access to the old data there. Renaming or deleting this folder will remove local editor history like extensions, chat history, etc…, but often resolved any performance issues.

We’re actively looking into what state grows especially large for some users to patch the issues.

I followed your instruction I hope it will improve the results, thanks for sharing

I dont have that issue on windows, but the latest version becomes extremly laggy (the cursor window) when you hit your pro limit!

When you send a question to agent, the question takes 10 seconds to send

You’re an angel from heaven. I deleted the contents in the History and workspaceStorage folders and didn’t lose my docs or rules. Immediately cleared the crashing and slowness. Also is the solution for this other issue. I’m gonna link to this for that issue.

Is this a related bug? Takes 4+ minutes to get a response. But i dont get a ā€œnot respondingā€ prompt.

Changing the name of the folders mentioned didnt do anything to fix my problem unforunately

Thanks a lot man! I can confidently say the crashing was due to a very long agent chat history. I was able to fix it by navigating to:

C:\Users\USERNAME\AppData\Roaming\Cursor\User\workspaceStorage\Workspace-Hash\Delete the files here

After identifying the correct workspace I just deleted the files within it directory and BOOM no more performance issues or crashes. :+1:

this solved the problem, thanks a lot!

Also didn’t resolve! Just paid for it. Everything is VERY SLOW.
