I used "Fit to Height" feature for screen adjustment. It adjusted things perfectly but i see a bug. A Grey vertical line appears in on the left side of screen while running on iPad. Attached file will explain it more. Is there any work around?
It can be from the background image, from its repetition. Try to hide it to see if it disappears. I would also recommend testing it on a real device, not on the previewer.
Sorry for being silly. Yes it was due to BG image. It was stretched to 10x. So some pixels might be causing the problem.
