Background Slideshow plugin suggestion

Hi guys.
This is my site .
The current background slideshow plugin is quite old and sometimes when the slides change the images blink or something like that. It is very annoying and I need to resolve this.
Can you please suggest me a full background plugin that works? All I need is it to have some sort of navigation icons and to be able to use it only on my home page, and also to be free, or at least a free version. I tried various plugins by now and I’m getting desperate. I also considered creating a slideshow via css, but honestly, it is way over my knowledge and capability.
Thank you in advance.
Best regards, Vlado!
