There is a slight graphical glitch you can see if you use a sticky piston behind an empty wall. For a brief moment,the piston will flicker and show what's behind the empty wall. It happens more often (or only?) with lag, but focusing the block (hitbox visible) behind the piston is always possible for a short bit.

When pistons move blocks, the blocks become invisible for a short period of time.

Rapidly moving slime or honey blocks allows the player to interact with blocks behind it, and causes certain blocks to disappear.

Cannot confirm.
Is it a matter of clock speed ?
@@unknown: Can you screenshot that setup before the piston moves ?
Can confirm transparency with the setup of Gary Closse while screenshotting, but cannot confirm transparency without doing screenshots.

Nope, not fixed completely. Lag makes it happen and I can always focus the block behind it for a bit.
Tip: Press F1 before screenshotting, that will hide the HUD and chat. And spam F2 while the piston is moving...
