I noticing this aliasing problem while listening to music today on my iPhone 12 Pro Max. On the Lock Screen, the album art is clearly aliasing (the full album art is also shown as a reference). I haven’t particularly noticed this on other phones, but I haven’t paid particular attention to it. If iOS isn’t using some type of anti-aliasing software when shrinking the album art and isn’t device specific, this seems like a pretty big oversight. Anybody else noticing any aliasing issues on your phone?
