When trying to view an image in landscape, the image will be zoomed in on the top of the image. Frequently it will be black space (at least in dark mode) even if the image doesn't have black space above it.
Attempting to zoom out the image or scroll around just exits the image.
I found that the limit image height option does the same thing in portrait mode.
I'm thinking that the x and y may be reversed somewhere in way the image width vs height is calculated. Not sure if it is model specific. I'm using a galaxy s21.
