Honey block texture changes while going up the side of the block

The texture changed when I was jumping up the block. It went away as soon as I got high enough. It was done up against 2 honey blocks, started with a jump. It seemed to have a bit of relation to the players' position

It also happened to the other faces while I was jumping on the honey block, including those on the opposite side of the honey block (at least, as far as I could tell)
