The Bug:

The faces of blocks retain the light levels of their original position for a short period of time when falling or being pushed by pistons.

As a result of this issue, block faces can appear to be rendered too dark. Additionally, this problem can be seen regardless of your smooth lighting setting, however, is much more noticeable when you have it disabled.

Steps to Reproduce:

• Build the setup as shown in the provided attachment. setup.png
• Activate the sticky piston using the lever and watch the lighting of the block faces of the calcite block closely as it's pushed.
• Take note as to whether or not the faces of blocks retain the light levels of their original position for a short period of time when falling or being pushed by pistons.

Observed Behavior:

The faces of blocks retain the light levels of their original position for a short period of time.

Expected Behavior:

The faces of blocks would not retain the light levels of their original position where appropriate.
