MINECRAFT: Mobs Appear Like a Black Shadow?

Hello.
Every time I've started up Minecraft today, mobs have appeared completely black to me, absolutely no color.

I should state that I'm using a resource pack and shader pack; however, I've confirmed this is not the problem since I have turned them both off for pure Vanilla MC and the issue still occurs.

The mobs aren't always completely black, I have to relaunch a few time to fix the issue, but this is tedious and not fun.

Anyone know a fix to this?
Thanks!

EMPHASIS: The packs are not the problems.

I've turned off both packs and played Vanilla MC, the problem still occurs. All mobs, creatures, etc., even treasure chests, are pure black.
I repeat: the packs are not the issue.
