I have black lines/shadows on bottom of macbook screen
I am using MacBook Pro with touch bar 2017 model. All of a sudden, there are translucent black lines and shadows appearing at the bottom of the screen. I went to the Apple Store to run a simple system check, but nothing seems to be wrong with it. Also, when I connect a second screen, the lines aren't there.
MacBook Pro 13″, macOS 12.2
