iPhone 15 pro video recording green screen bug

Hello, since I have the iPhone 15 pro I’m experiencing a big problem when I record 4k videos with the iPhone. Some of the videos (let’s say 1 in every 20 videos) are bugged with green screen and awkward shape. The actual recording is on the upper right corner of the screen and the rest is just bugged with green, repeating video, and so on. I already updated to IOS 17.1.1. This only happen with my iPhone 15 pro… with the previous iPhone it was everything ok!! I’m seriously thinking in returning my iPhone. The strange thing is that just happen to some videos! So the camera is working OK i think. It must be software. Someone knows how to solve it? Thank you so much.
