Jeb Door Creates really weird piston glitch, that is possible new x-ray

I expected me to be pushed out of the way of the piston, or get stuck withing the piston itself.

 

I was stuck in between the piston head and the piston block, causing a weird glitch to make a diagonal line to see through the block. And seems to make an x-ray glitch. The last two photos have 3 more blocks added on and you can see right through them. That means all you have to be is in that part of the piston head to see right through any block in front of you

 

1. Create a normal jeb door with 3 tick repeaters
2. Have your crosshair to be on the lever and flick it.
3. Walk in and stop right where piston will be.
4. Wait for the pistons to go back to where they were
