Performance issues / image flickering

[cmarlow]

Thanks so much for getting back to me! My navigation had a fixed position,
so to it, I added:
-webkit-transform: translate3d(0, 0, 0);
transform: translate3d(0, 0, 0);

It seemed to clear up the issue completely! I'm thinking there was some way
that the browser was trying to add the effect to the header.

Thanks again for your time.

You could try taking out some of the GPU hacks by removing the lines that
add translate3d CSS both here

and here

Let me know if that does anything for you.

Strange, I have not encountered this issue before. What browser are you using? Could this be a GPU issue?

[schuette]

Firefox... GPU issue is possible, although I’ve seen it happen on my colleagues computer too. He has a new Mac Pro with Thunderbolt display. I’m using 2013 Macbook Pro with retina display.

I'm having the exact same issue. Using Firefox 35.0.1 on a 2013 MacBook Air. Like schuette described, the background parallax images temporarily disappear, sometimes with horizontal lines streaming across. The images reappear when I stop scrolling. It only happens sometimes. I should also note that I'm using a mobile-first responsive design. For reference, here is a dev link: http://blwork.com/maxpoint/dev/

@schuette did this solve your issue as well?

[schuette]

Yes, I've been testing all weekend and haven't noticed the issue anymore, so I think it's safe to say it's fixed. Thanks!

Cool, good to hear.
