I was playing earlier and realized that my portrait had a very unusual texture, almost like the skin of different types of objects, (if you get what I mean)
Also, the Sniped Stranger hat Portrait Glitch. Ill have a link to that too.

Happens to me too, all the time. Sometimes it's missing, sometimes it's glitched, sometimes it's just fine.
