Created attachment 421256 [details] Image showing webp single and double color imgs not rendering in Safari Some low color WebP images are not rendering. I have not narrowed down all the scenarios where the issue arises, but the two examples of the issue I have been able to recreate are with webp images that are single or double color (I just tested two horizontal color blocks stacked). The images will not render in Mac Safari or iOS Safari. They render correctly on other platforms (I tested Mac Chrome and Android). I have created a demo of the issue in a CodePen: https://codepen.io/lokesh/pen/VwmMONr

I cannot reproduce this. What version of iOS and macOS are you seeing this with? Can you try the latest beta? In any case, this is almost certainly an issue in image decoding libraries below WebKit, and as such, it's better to report via https://feedbackassistant.apple.com for Apple engineers to take a look. One way to confirm is to save the image and open it in Preview.app on a Mac. If tat fails too, that's definitely an underlying issue.

I can't reproduce this bug either on macOS Big Sur or iOS 14.
