Dropped items upon death is invisible

If you die near spawn point and you respawn, dropped items is invisible but you can pickup the invisible loot. This Happens also for XP orbs. Because the loot is invisible, I can't give any screenshot

What I expected : The dropped items must display.
What happened : The dropped items don't display.

How to reproduce :

1. During the night, put a bed and sleep
2. Put some items in your inventory
3. Die and respawn
