Does this stop you from using Cursor

Hey, I haven’t noticed this behavior myself. However, I can suggest that it might happen in long chats when not all messages have fully loaded yet. When you scroll to a part of the chat history that hasn’t been loaded, you might experience some lag. Could you confirm if this is what’s happening in your case?

This is likely due to terminal tool call rendering:
