If a 3 block with nether portal crosses a chunk line it can glitch out and show only one part of the portal, I noticed one players portal was glitched out. While using a utility shader i checked chunk bounds near glitched portal and realized the glitched portal was right over a chunk border. One side of the chunk boarder had no portal blocks, the other side of the chunk border did have portal blocks. Was very strange.
