Game doesn't render shadows on fancy singleplayer, partly multiplayer

I just noticed that when your on fancy, the game never renders your shadow and even for mobs. When on multiplayers, you can see all shadows for entities/players just fine. But still, you cant see your shadow on multiplayer.

Steps to reproduce SINGLEPLAYER:
1. Switch to fancy mode
2. Press F5 to view the back camera of your person
Notice that all mob/player shadows don't render at all.
