CSS Backdrop-Filter

The sources provide an extensive technical explanation of the CSS backdrop-filter property within Google Chrome's Blink rendering engine. This deep dive details how the feature, which allows filters like blur or brightness to be applied to content behind an element, is implemented via Blink's compositing and GPU pipeline, involving the creation of EffectNodes and RenderPasses. Much of the discussion focuses on interoperability issues and performance optimizations, particularly how Blink addressed the notorious edge flicker artifact by adopting the mirror edge sampling mode and ensuring that the effect correctly respects stacking contexts and clipping (like border-radius), while also cautioning developers about the significant performance cost associated with the feature.
