This seems to manifest as fuzziness in layout/reftests/css-blending/mix-blend-mode-and-filter.svg like it is sampling something in the filter at a wrong offset, once SWGL enabled KHR_advanced_blend_equation support. As per gw on matrix: ``` I'm not entirely surprised, I'm finding it difficult to understand how any of the mix-blend stuff works in the presence of raster roots (which svg filters introduce) at the moment! (well, it doesn't work - I've already been able to create simple test cases that are completely broken with the existing impl) ```
