Floating Blocks (in ground once broken) appear darker or lighter depending the angle you look at them.
*What I expected to happen was...: Them to have a uniform color.
*What actually happened was...: They go from iluminated to total dark.
Steps to Reproduce:
1. Dropping any block in the floor should reproduce it.
2. Check attached images.
Can't confirm in 1.8.3. Are you still experiencing the issue?
