Say I copy/paste a picture on top of another picture. Whenever I go to resize the image, the image flips either horizontally or vertically. All I'm doing is simply shrinking or expanding the image using the dots in the corners of the image, but then the image randomly flips upside down or reverses itself for no reason. Preview on my previous Macbook did not do this. I have a 2015 refurbished Macbook Pro operating on High Sierra.
