iPad Safari Firstload image problems

[Jori]

Hi, I am webmaster of several Wordpress websites. Some of them use sliders, and they don't work on firstload any longer if browsing with Safari on iOS 8. Only when loading at least a second time (sometimes a third or fourth time), everything is fine. Problem is that images are shown on wrong places on first loading (images are shown on image-places but not the images that should be loaded there but other images, and this is not only a problem within the sliders but even in other image places). Other browsers like Chrome and Opera work fine on iOS 8, it only seems to be a Safari problem. I have already changed my browser on iPad because I was heavy frustrated but as a webmaster I really would like to know how to get this problem right again.
