Oh wow Ryan, this has been going on for some 5+ yrs for you! I’ve recently ditched FCS for Premiere Pro CC v8 and experiencing exactly the same issues. Thankfully my pink vertical line [albeit in my case it’s more like 20% margin right side of frame] appears only at the end of my edit. So, not being a particularly technical type, I solved the problem by creating a blank [black] title card at the end of my edit and simply exported a couple of frames shy of the end blank card. Geez, I wonder why this happens though?!
