Help with a parallax web site that is flashing and blinking when it shouldn't be.

I have a parallax scrolling single-page site that I am working on, and for some reason, when you scroll down to the section called "services" or below (3rd and 4th sections), the page has a constant flash effect occurring. The contact section has even more pronounced "flashing".

I have no idea what is causing the flashing effect, nor any idea what to modify to get the site to stop flashing.

The site is under development on my local machine and can be accessed at

By clicking on "SERVICES" in the navbar, the page scrolls down to the specific section and then the flashing begins.

It is a simple HTML file with jQuery and a few jQuery plugins.

I would copy code here, but I don't even know what to copy and I don't want to bore everyone with the entire code.

If someone can point me in the right direction as to what I should copy here, I'll add it. Otherwise, if someone has any idea what the problem is and how I can solve it, I'd really appreciate it.

FYI, using Firebug in Firefox and Web Inspector in Chrome and Safari, I was unable to find the problem. There are no errors or conflicts that I can find. The CSS is pre-processed using LESS and compiles without errors. The CSS is not minified and has debugging comments if that helps.

The plugins being used are:

contact-form.js
jquery.flexslider.js
jquery.inview.js
jquery.prettyPhoto.js
jquery.sticky.js
nbw-parallax.js
smooth-scroll.js

Also using 3 web fonts (extensions not included in the list for simplicity of reading):
BEBAS
fontawesome
League_Gothic

I uploaded a short screencast showing what I mean.

If you pause the video and advance frame by frame, you will notice that (around the 5s mark) there is a flash and it seems that the contents of the viewport gets momentarily hidden revealing the logo and company name from the very top of the page on a white background (but since the text is white, you can't read the text).

Your page took too long to load and I closed it. I recommend simplifying it, particularly if it is a home page. Do you really need all those plugins/features in a single page?

Hi Andrew:

I moved the site off my local machine and onto my web host. My local machine is just too slow.

It's a parallax site and the plugins are needed for the purpose of implementing the parallax scrolling and for the slide-show.

Maybe you can try it now.
