So i found this custom 3d block models are rendering incorrectly on different Y levels

in image 1, Y = 63 and Y = 64
On Y = 63 the texture is rendering weird and on Y = 64 the texture has no problem.

in image 2, Y = 63 The custom model trident image is blurred.

in image 2.1, Y = 64 The custom model trident renders without any problem.

Same problem in image 3, Y = 64 and in image 3.1 Y = 63
