Seen on iPad running 12.0.1 (16A404). Ensure that the Smart Invert Colors accessibility shortcut is enabled. You can enable it under Settings > General > Accessibility > Accessibility Shortcut. Perform the following: 1. Visit <https://old.reddit.com/>. 2. Triple tap the Home button to enable Smart Invert Colors. 3. Tap a hyperlink of a post. 4. Swipe back. Then some of the images will be corrupted. If you do not see this the first time then try tapping another post and swiping back and/ swipe forward and then swipe back. For some reason this bug seems to only happen when Smart Invert Colors is enabled or at least when this settings is enabled the image corruption is more noticeable.
