Hey, thanks for the report. I can see the video has artifacts. This looks like a GPU rendering issue in the Chromium layer. We had a similar report last week that was fixed by updating GPU drivers: Cursor Visual IDE Breaking Bug
Two options:
Update your GPU drivers. This solved it in the previous case with an NVIDIA RTX 3060.
Disable hardware acceleration. Start Cursor with the --disable-gpu flag, or in Cursor Settings search for Disable Hardware Acceleration.
What GPU are you using, and what driver version are you on? Let me know if either option helps.
