its too difficult to explain you should try it on low resolution or low-end devices render dragon graphics

the shattery pixels or whatever that called so I try high pc on the school it's no shattery pixels but the low devices can't handle it so I change to 16 chunks to see clearly the every pixels from 30 blocks distance the game is laggy and shattery graphical like a gameplay menu caves and cliffs panorama graphics in this case I think it's 64-bit seeds or other reason to add on Bedrock
