I am using a mod pack on a launcher and when I am in game these odd block block and partial entity models appear in the center of my character and fade away slowly after a few seconds. It doesn't only happen to my player but also to other mobs. Sometimes it is the model for the creeper head block or zombie head and sometimes it looks to be a skeleton arm or something else. They are random and USUALLY (not always) appear after I break a block while looking at a downwards angle. I have no clue what the problem is. Any help is appreciated.

I believe the hats mod is doing this either remove the mod (%appdata%>.technic>modpacks>(the pack)>Mods) or diable hats in game.
Have a great one!
