I use a slideshow with one background image per slide in full width mode and responsive. it worked fine until now, where I discovered that the background images automatic scaling and cropping does not work anymore on safari and chrome. however it still works fine when using firefox. I haven't tested other browsers. After searching I discovered that the calculation of the image "style" in the div "md-maininmg" was not processed on safari nor chrome. I have now no clue what's going on and would really appreciate some help.
I tried version md-slider 2.11 and 2.15, none works.
