Source code
Given a container of width < 100%, an overlay with -webkit-backdrop-filter: blur() applied, and an element underneath the overlay with a CSS animation applied, triggering that animation causes rendering distortion to occur. While this issue can be reproduced when other backdrop-filters are applied, it is most prominent with blur().
Example: <a href="http://liamdbz.com/webkit">http://liamdbz.com/webkit</a>
