I just said what triggers it, and when I think of it I think I know why. Also I did not know if it was a bug or meant to be.
You know when you get killed your kinda frozen at the spot where you got killed for a few seconds before you start specing who ever killed you.
( death cam or something ) And before that ends you get respawned with the same crocked view. At least that's my thought on the matter.
So removing death cam might fix it.
