Chrome not showing custom background in header and content (color content)

Hi, you can see the screenshot of the errors in Chrome v29 http://bit.ly/16QlCie
my test site http://lapolla.dreamhosters.com/

the two plugins i’m using are Gravity Forms and the top bar is from “Nice Notifications” http://codecanyon.net/item/nice-notifications-wordpress-notification-bars/5061498

Header:
I have a custom gradient that appears fine when I’m at the top of the screen for the background of the header. However, once I scroll down and the menu sticks and becomes smaller, the background disappears and just the white background color shows. Firefox v24 and IE9 the background gradient follows as you scroll down.

For the content on the page, the “Advanced Slider”, and any custom images used in “Color Content” are blank. I’ve cleared my cache a good 10 times, reset my computer 2x, still nothing shows. Both Firefox v24 and IE9 show the content.
