The bug
The big dripleaf stem's texture is stretched up and down. It might be hard to tell but the pixels aren't perfectly square. big_dripleaf_stem and big_dripleaf are both affected.

After doing some examining, it doesn't look so much like the model is stretched vertically - otherwise, each pixel would be taller than that of any other block - but rather, the model is squished horizontally, making it thinner than it should be (and also producing the same effect with the pixels).
