Water generation glitch (random 1x3 2 deep gaps in the sea.)

Put the summary of the bug you're having here
The generation glitch/bug if finding random 1x3 gaps which are 2 deep in the ocean when tp'ing to far distances

What I expected to happen was for the generation to be quick and easy.
Describe what you thought should happen here

What actually happened was: that generation was pretty slow (I was on a fast PC/Mac) and occasional generation glitches and gaps in random places, mainly in the ocean
Describe what happened here

Steps to Reproduce:
1. Tp to a far distance (or move a far distance quicker than the game generates

2. Move down to the ground so the ground loads (Have render distance to 16 chunks)
3.You may notice some gaps or ungenerated areas.
