When using a super fast redstone pulse with command blocks I tried to place a piston near the machine and the texture was glitching (it happens with both sticky and regular pistons).
What I expected to happen was...:
An incredibly loud piston noise and the piston going in and out very quickly

What actually happened was...:
No sounds at all and the piston texture glitching-

Steps to Reproduce:
1- place a command block and put in the following command: /setblock ~1 ~ ~ air (it depends on where you place the command block, you can use relative coords or the normal ones. Just make sure that the air is going to be placed next to the command block).
2- place another command block and make sure that is next to where the air block is going to be placed.
3- put in the following command: /setblock _-1 ~ redstone_block (still, it depends on where you placed the first command block. Plus, this command block needs to overwrite the air block)
4- place a redstone torch in the air block between the command blocks
5- when the super fast pulse is working (to make sure it's working you should have the chat full of "block placed") place a sticky or normal piston so that they are powered by the redstone block.

Here's a screenshot.
