Your pic of the close-up is too grainy for me to tell when I zoom in to look at it. I see the slightly curved line you are talking about but there's no way to tell what it is or how it occurred based on your pic IMHO. Looks like maybe a couple of die chips at the top right position of the window but other than that I'm not sure.
