Easy Slider Full-width shows wrong flow of slides

Hello there,

Some websites that I developed uses the Enfold theme with the Easy Slider Full-width. I did not experienced any real problems with the Easy Slider Full-width in the beginning but since a while I can see some of the websites I developed shows a “wrong flow of slides”. The slideshow containing slides with images are not properly displayed; the first slide renders correctly, however when the next slides run from right to left (slide to side), it renders nothing and a large white space can be seen, within milliseconds the image appears. It only takes milliseconds to appear but you can see the problem quite brightly.

I configured the slideshow to loop but when the first slide begins again, and the slides after it, the slides are presented correctly.

You can check the problem here: website. I have to remark: you can view the problem only when you empty the cache of that page (for instance doing a hard browser refresh).

I also noticed that the ul.avia-slideshow-inner list items do not start with their full CSS code if you load the slideshow the first time, perhaps it has something to do with the CSS code? Strangely enough not all the Enfold websites I developed has this problem.

Any help of course would be appreciated :-)
