I tried, but I still cannot reproduce it. I do see the spurious lines very very briefly when scrolling the hightlighted area into the viewport, but they are always removed. Still, I like your modification from Feb 25, because I don't think that the border rectangle should be drawn across the highlight region if that region is only partially visible.
