Window Streaks with Power Sunscreen for Rear Side Windows
 

Some thoughts please...2014 Panamera 4S. Have power sunscreen for rear side windows (and power sunscreen behind rear seats). Kids love the feature to "darken" the rear when the sun is bright (not very often here in the Pacific Northwest!). I've noticed 3 vertical "streaks" on the glass from the screens going up and down. Tried to attach a picture but didn't show well. Initially thought it was only the passenger rear window but also see it more faintly on the drivers rear window as well. Easily wipes clean but definitely noticeable when the screens are used in the rear. Bothering me. Is this normal? Do others with this option see the same thing? Car still under factory warranty so not sure if the screens need adjustment/replacing. Am I being too picky and will the dealer dismiss this as normal use? Thanks in advance.
