I’m aware that there is bugs with translucency but have not found same bug report.
So, there is sample, back facing polys rendering above front facing. In some places sort seems working (depends on angle between normal of a polygons(front/back) and/or camera vector.
Hey S-ed -
This is a known limitation to the rendered translucency in the engine. We are striving to provide more accurate translucency rendering, but for a leaves setup like the Bush you are showing in your exmaple I would favor using an Opacity Mask or a Subsurface shader.
Thank You You Again for your report.
