Pistons (Sticky and Non-Sticky)

When I was playing Minecraft today I seen there was a texture glitch with the Pistons. The pistons still work properly but it's only a texture glitch. They only appear to glitch out when the pistons face to the West it seems. My gamer tag is TMH KiLLa KyLe2 for the Xbox One S. If your able to identify this glitch please email me at
