Jungle Biomes are extremely cluttered

I was playing 18w07a and noticed that the jungle biome was almost impossible to travel due to there being leaves and trees everywhere.

I compared it to 1.12.2 and I'm almost certain the snapshot version is way more cluttered.

This also caused me bad fps drops and stutters.
