Flaming Arrows and Beacon Texture Don't Mix

Get a bow that has an enchantment of fire aspect. Make a pyramid with an active beacon. Shoot an arrow directly at the beacon block, and the "stream" from it will start acting weird and will look rigid and messy. The attached pictures are intended to show this. (This may be a little hard to do.) Once the arrow is removed it will stay that way, unless you log-out and log back in.
