Why is my iPhone 14 Pro camera doing this all of a sudden?

Hi all! I just have a question about this weird new edge mirroring effect that I am seeing when taking pictures on my iPhone 14 pro. I'm using the camera app Reeflex and it seemed like half or more of the pictures I took today had this problem. I have an example below. This has not been happening until today. I did recently update my iPhone to iOS 16.5 from like iOS 16.3 or something but other than that I don't think I changed any settings. I even bought another camera app "Camera M" for $8 to see if it was just Reeflex but it happened in that one too. It does not happen however so far in the built in camera app. But why would 2 different 3rd party camera apps from different developers start do the same weird thing? Have any of you guys experienced this issue? It makes it look like some sort of kaleidoscope but only at the sides. These pictures were taken I believe on the telephoto lens in ProRaw format. Please does anyone have any input or ideas about why this might be happening? Thank you very much in advance for any help.
