      Description

      The bug

      Pistons are no longer transparent when not extended. When triggering just a few pistons in a simple redstone circuit the light updates cause extreme client and server lag.

      How to reproduce

      1. Make a box / room from opaque, solid blocks so that no light can enter
      2. Replace one block from the ceiling with a piston, pointing up or down
      3. Toggle the piston state with a lever / button, for example

       

       The client and the server will experience severe lag, beacuse of the excessive light updates

       When multiple pistons with slime blocks are working in a redstone circuit, the performance is decreased drastically
