Hey Metalord, I've personally had this issue (I think it was last year or so. A couple of times at least). On my side the problem got fixed on its own after some time. But I would suggest that you relog your Facebook profile through the web.
I can't be sure if this will fix the problem but seeing as the issue is that FB profile pictures can't properly load for some reason, I'd wager that the server might be having difficulties communicating with Facebook or your FB profile. So give your profile a relog.
