-the fact is the grass is buried in the blocks in the 2 editions

as you can see from the pictures below the grass depth in the block is not the same as java.

in both edition the feature behaves diffenrently : in bedrock version the grass is sunken by 5 pixels whereas in java it is only sunken by 1.5 pixels

how does this parity impact the bedrock version?

-it makes the grass look even smaller than it already is

-it causes lag and reduces performance

-and this gives a very disturbing rendering as a java player for a very long time
