I'm not as familiar with blender 2.79, but ill try to look into it. Is there options such as alpha blend/alpha clip/alpha hashed?
Edit: Roy's hair in particular still looks weird, but generally you have to go to your material properties, then scroll down to settings, then view port alpha and change it to alpha clip.
