I don't know if this is also fixed in 0.25, but I get weird render bugs with two shaders: Raspberry and MollyVX. Both are made by rutherin.

Raspberry: (Notice that my design are enlarged and possibly mirrored)

MollyVX: (Same thing, the lighting is actually an Optifine problem)

MollyVX is path tracing and is hard to be compatible with.
