Slider issue. Pictures and titles/captions loading delay.

Hi, I am looking at your theme “Super construction”. I find that, in the demo, the slider pictures are all loaded at the same time and displayed in order, then the titles and descriptions are also all loaded and displayed on the left on top of each other. Both stay around 1 second before the slide starts working normally. I notice that in the business point theme too. I would like to use your theme but I that this is an issue and doesn’t give a good impression to the end user. Is there a fix?
