Description

I narrowed down the issue to the Main call of ShadowProjectionPixelShader, and tested (on 4.26 and 4.27) a combo of different material and light shadow settings, as well as enabling transmission on the light for the the SUBPIXEL_SHADOW enabled shaders, but couldn't get to the bottom of it.
