iPhone 14 Pro Max Purple Lines on Camera Screen

Just bought this iPhone 14 pro max in March, the other day I noticed when I zoom in to 3x or more on my camera app, little purple lines go all the way across the screen. This does not happen on apps that use the camera (Snapchat, Facebook etc) just on the camera app. I have updated my phone and done a full factory reset and it hasn’t fixed the issue.
