Hello!

Press Shift + Command + 3 to take a screenshot. Resize the screenshot to confirm whether the anomaly is caused by a software issue or due to a damaged screen.

If it is caused by a software issue, then consider updating (that is if your MacBook supports macOS BigSur), before attempting any other solutions.

If it is due to a hardware problem, then refer to this article:

Hope this helps!
