Thank you for the update. As we made recently already improvements but I would like to collect more information so we can reproduce your issue and fix it as well.
Could you share more info on what you do with SSH and how you use it?
As we don’t have access to your computer we cant really see what is happening there and rely on your help.
Unfortunately I do not have sufficient information to help you, but I would like to help you:
Do you connect from Cursor to an SSH server?
Do you use SSH to connect to a remote machine and there use Cursor?
Could you update to 1.3.8 as it contains several improvements for performance.
Does the issue occur also on 1.3.8?
A bit before it usually would get stuck, please check Help > Open Process Explorer and post here the screenshot so we can check which part consumes more CPU or memory.
