In addition to using background-attachment:fixed (which is addressed by bug 1166301), this page seems to use a parallax effect to make the background scroll more slowly than the main page contents. I filed bug 1201231 to track parallax issues, making this depend on that bug in addition to bug 1166301.

I've noticed similar looking issues in other websites since I have filed this and thought they're all bug 1166301.  Does this mean that I should file bugs for each one?

I would wait until bug 1166301 lands (hopefully pretty soon), and then file bugs for pages that are still misbehaving.
This is still fairly jittery because we're repainting the large images on every scroll.
Bug 1201333 would allow us to use ImageLayers, which would be much faster.
I'm not seeing jitter here any more. Ehsan, is it still jittery for you?

Yes.

(I'm not sure if I can provide any helpful info, let me know if that's the case!)
Bug 927228 will improve this a lot.

With that fixed, it's still a little jittery on my machine, due to bug 1209970 (in a way that would be fixed by bug 1221069). Also, there's a small lag when I start to scroll, because the display port is enlarged by apz.y_skate_highmem_adjust. With apz.y_skate_highmem_adjust set to 0 it feels a lot better.
And now that we're almost done here, the website has changed and no longer has a parallax effect.
Well, we have enough other bugs open for sites with the parallax effect.
