Cursor window not responding - stalling

Bug Reports
1

Describe the Bug

The bug is that cursor becomes unresponsive. This is when not doing any AI query, just clicking on the cursor code window (or terminal). It can take several seconds for something to happen, like allowing to scroll the window or type a character. It gets so bad the windows dialog for Application not responding, Quit or Wait pops up. Not even the Windows Message loop is working.

Steps to Reproduce

The issue reproduces very consistently for me, but I have a setup where cursor runs on my windows machine, remote connected to a linux machine (where the code is).

Expected Behavior

cursor should be responsive, allow to scroll the code, type characters and even switch to different code windows (Ctrl Tab)

Additional Information

When the issue happens, I check the developer tools window and I see lots of networking calls to full_stripe_profile (likely checking account validation). On the timing of this call I see long waits on Queuing and Stalling, but never over 100ms of actually waiting for server response.

I am thinking this could be tied to disk. I have been doing some debugger profiling (stopping cursor on a debugger). I almost always, when stuck, I get this callstack:

cursor_flush
cursor_flush681Ă—333 12.4 KB

Looking at the taskmanager at the same time, cursor spends some time doing disk writes, which makes sense with sqlite:

cursor_task
cursor_task849Ă—132 9.83 KB

Why does it need to save so often, so much data?

Hey, we released a new update 1.3.7. Try updating and let me know if the issue persists.

I have updated to 1.3.7, I am on 1.3.9 now and similar thing is happening. I see a spike in disk access, the window does a hiccup and is not responding for a few seconds and it recovers.

I had not touched the cursor window in a while (I was out for lunch) and I was only switching to a different terminal.

hi @LawrenceI does this repeat also on 1.4.2 (the current latest version)?

I just upgraded to the latest version. Some of it is happening, I’ll see in a few more hours of work.

Latest version is still happening. Upon closer inspection, it seems all threads are waiting and the ChromeIOChild thread is waiting for IO

This still happens, after a while of working it keeps getting increasingly worse. Is there some setting I could try, reduce the frequency of saving stuff to disk?

10

To add insult to injury, I was typing today, cursor stalled, windows opened the quit dialog, it caught my typing, and closed the cursor with my debug session and everything on it. Ufff…

11

@LawrenceI sorry to hear that, we are still working on improvements. I updated the internal bug report with details you posted.

Sometimes it gets quite bad, switching files, typing my prompts to the AI, moving the cursor.
I have tried to kick out all extensions.

My setup is a bit peculiar:
main workstation is a windows machine, but all my projects and code run on linux
I have multiple instances of cursor, because each project is self contained (although they talk to each other). The instances are usually up because I leave the debugger running or some process on the terminal (I can catch more issues).

@LawrenceI In case you are on the Beta release channel, we have sent out 1.4.5 which has performance fixes.
