Slider Problem when page load

Hi , I am new to webdevelopment and chose the Klasik theme, everthing works fine except for the homepage slider.

Here is the link to the site:

Everytime when pageload the slider would start blinking instead of showing the image properly. I have to click the arrows once first in order to show the original slider image.

I found this problem on Chrome but seems not on Safari.

Can anyone please help!!

Thanks
