I have these APNGs on my art portfolio website. They look fine on desktop Safari, but occasionally flicker (changes in color and parts of the APNG disappear) in safari on iOS.
Another person also viewed it on mobile, and they experience the same problem.
I'm not sure if the problem is in my code, or in my images.
