Mr_Owlalmost certainly has something to do with alt-tabbing, this game does some really wonky stuff when you do that.
I run in borderless windowed mode though, not fullscreen. It shouldn't have done anything that wonky. I think the chat window was up because I did that to release the cursor for tabbing. I think third person FOV is higher than first person, but it didn't re-apply the first person for whatever reason at the end of the taunt.
Screenshot comparison in same exact spot at normal 90 FOV.
