Describe the Bug
I have noticed the past updates to cursor, when cursor agents are making active edit’s the performance of cursor becomes laggyer and laggyer, it has to due from the session chat. if a user opens a new chat the performance issues stop.
but it get’s to a point where it’s unbearable
Steps to Reproduce
Long sessions, with huge edit’s, you will start to notice the response time and cursor start to be very unstable, leading to crashes, and the IDE not working and the application taking at least 10 seconds to respond
Expected Behavior
Not exactly sure but it has to do with the chat system, causing the lag and performance drop, it should not degrade performance after long sessions
