I've had this happen to me as well, JoeBlack...and it's not, to me anyways, new to this update. Rather...it's usually an indication that VUE (and my 'puter) are telling me that I've just about reached the limit sizewise of what I'm going to be able to do with that particular render...which in my case is just about every one I do...LOL! I realize that this doesn't solve your problem, but just wanted to let ya know that you are NOT alone there '-)!
