Funny thing, on my Ipad I can see 5 lines when I take photo, I even see them stuttering on this page using bare eye, so it might be some animation / Javascript issue or somehow my Ipad turns to 24Hz mode, which shouldn’t happen on a moving webpage.
E: Nevermind, I think it’s due to shutter speed and low lighting at my room, when I set it to higher frequency there’s just one line. Anyway, I hope I don’t start getting eyestrains with my IPad now, when I saw it 🙂
