I managed to resolve it by myself. Something was wrong with the current slide, i’ve created a new one and it is visible on all browsers.
I’ve tested it a little more. So basicly forger the part with netrenderer, it doesnt show slider whatsoever while it generates a preview.
I’ve setup Internet Explorer 10 on my PC and it shows the text layers like on image shown above, and it doesnt load the background image, instead theres an X and the name of image in the top left corner.
Normaly shows and loads in all other browsers and Version 11 IE.
Found out that demo slider is shown normaly, but this custom one isnt, even with the same settings.
