I forgot to disable other resourcepacks in screenshot, but I'm sure it can be reproduced in vanilla environment.

Can confirm in 26.3-snapshot-1. Actually the renderer is strange when X/Z>16777216, a little bit similar to the stripe land on Bedrock Edition. Why Mojang still set world border limit to 2*29999968 instead of 2*16777216 to deal with this bug? lol
