Valence Version
What You Did
I run and slightly modified version of the anvil_loading example. I changed the spawn not to be at 0 0, but it was not far from 0 0.

}What Went Wrong
On clients with sodium or starlight or both installed, the chunks didn't shown up correctly and the client was long stuck at the "Loading terrain..." screen. I also tried this with different maps, so I can say for sure that this isn't a problem of this map.
I disused this problem on the discord server, a other user can reproduce this problem.
This Issue only occur on clients with sodium or starlight installed. On a vanilla client it works fine.
Additional Information
