when it's on, it doesn't render sugar canes on grass. AND there is a second bug, i use custom sugar cane model (by a resource pack) and it doesn't load/use it on sand for sugar cane. so it doesn't respect what model used.

and ah, it doesn't support most of the mods' plants. such like biomes o plenty plants, or forestry plants, or dungeon tactics plants, etc...
could you add a check if it's a plant? it would be cool

I'm having this issue too with the surgarcane. With and without a resource pack. Also I think it should affect all leaves as well.
