What's Wrong?

When the agent is generating ANYTHING, it seemingly rapidly scrolls to the top and bottom and it looks incredibly wonky. THere's no way to describe it other than in the video I sent. It happens anytime you click enter on an agent action and it usually stops after a few seconds. If it glitches for long enough my entire Cursor crashes.

What Should Happen?

It should literally just retain the viewpoint on the bottom of the screen and not give me a seizure.
