Render Distance decreases from 12 chunks to 5 chunks

When I would be playing in my world, for some reason the render distance would go very low when the maximum is at 12 chunks. I suspect it would go to 5 chunks. The world would be at 12 chunks, then freeze for like a second, and then it would change to 5 chunks when the setting would already be at 12 chunks. This has been an issue for me for a long time. The two videos are examples.
