    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 and is now on a dev server

    http://clients.ergonomiq.net/polarisrm/
    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).

    I haven't looked at the page as I'm on an iPhone, don't have access to a PC for a couple of days but I have seen this behaviour before.

    One client had a similar issue when they had used numerous JS files from numerous sources. Although it wasn't kicking up any errors ... Th effect was obvious.

    I ended up just removing references to the .js files one at a time... Knowing it was going to disable some of the functionality... But still, when you use other people's code, its really hard to tell exactly what they were thinking or trying to accomplish.

    I got lucky and was able to resolve by just loading a certain .js file last and it seems to fix the issue. The JS code was a mess and there was actually a lot of redundant stuff that was t needed, but I'm the type of person that doesn't try to fix what isn't broke, so once I got it working, I left it alone.

    I've redone my clients site since and did not reuse any of his inks stuff remnant he got from who knows where...

    Might just want to try some basic troubleshooting to determine which file(s) may be causing some conflicts.
