On average I get around 75 fps but when chopping trees (especially ones with large amounts of leaves such as dark oak and jungle trees), my frame rate tanks anywhere from 2-10 fps. The issue persists until all leaves have decayed. The closer to the decaying blocks I am, the worse the drop in frames. This is especially bad in jungle biomes when lots of leaves are updated from a single tree decaying.

The three attached images show fps graph before the logs of trees have been destroyed, looking at the decaying leaf blocks from a distance, and standing next to the decaying leaf blocks.

My hardware:

CPU: Intel i7-6700k

GPU: Nvidia GTX 1060

To Reproduce:

1. Chop down trees and wait for leaves to begin to decay.
