Macbook Air box outline

Hi,

I've been using my macbook for over a year and I've never had this issue before but everytime I visit my home screen I can see a black box outline and I can see it on my wallpaper. I have a macOS Catalina (version 10.15.7) can you please help me fix this issue.


MacBook Air 13″, macOS 10.15
