Screen stutter and freeze after chat completion during 15-30 minutes of Cursor usage

Describe the Bug

When launching Cursor, everything initially works as expected. However, after a few minutes of usage, I begin experiencing screen stutter or brief freezes specifically when a chat finishes. The freezes last between 5 to 30 seconds and become progressively worse the longer the session remains open.

Steps to Reproduce

Start Cursor

Use it normally for a few minutes

Observe the screen behavior when a chat finishes

Expected Behavior

No screen stutter or freezing during or after chat completion, regardless of session length.

Operating System

Windows 10/11

Current Cursor Version (Menu → About Cursor → Copy)
