I would create a new world, and some new chunks would load, but most of the new chunks don't load when they should load. I would even walk over to the unloaded area, break/place a block, and nothing would load.

To make them load, I would have to go to video settings and change the render distance to a different value, and then back to the value I had it set on.

I have a video showing this:
