Looks like it’s doing that because of the fadeup effect. You may already know this, but the fadeup effect is designed to have the content fadein-up when you scroll to each section. Since the first section has it added to the code (slider), it’s waiting on you to scroll so the effect can kick in.
I would probably just remove it from the 1st and/or 2nd widgets. You can easily remove this from the front-page.php widget sections. Look for the fadeup-effect class in the slider section and remove it –
genesis_widget_area( 'slider', array(
'before' => '<div class="slider"><div class="front-page-1"><div class="image-section"><div class="flexible-widgets widget-area fadeup-effect"><div class="wrap">',
'after' => '</div></div></div></div></div>',
) );
Let me know if that fixes it.
