I've pregenerated out to ~580 chunks around 0,0. When starting up the world in singleplayer with 512 DH render, everything seems to render around me (and in the distance) at first. Once I start moving around, terrain disappears around me, seemingly equal to the vanilla render distance I have set. Sometimes it's everything around me in that range, other times it's just certain areas. It happens whether or not I use a vanilla render of 8 or 32, and whether or not I use shaders.
To be clear, the LOD's are loaded in the distance, but then vanish as they enter my vanilla render distance. If I stay still, it will eventually load in around me. I'm currently using Bliss Shaders, but it still happens with Complementary. The game itself isn't crashing.
CPU: 12th Gen i9-12900K
GPU: GeForce RTX 3090
RAM: Corsair Dominator Platinum DDR5 32GB
This happens whether or not I assign 12GB or 24GB to Minecraft in the starting arguments.

Also a side question - how long should it take to load the 512 render distance? It's taking 5+ minutes for the pregenerated terrain, but maybe that's normal?
Thanks in advance for any help.
