Optimising background-attachment: fixed

Hi Treehouse,

I'm working on a project that involves 2 instances of background-attachment: fixed. Ideally I'd like a third in there but I've turned it off for now as it's just a bit too much.

I know this question has been asked before and I've been digging around a lot trying to find an answer but:

Is there a way to optimise performance when using this property? The issue is that the page becomes a bit jittery when scrolling up and down.

I've used the will-change: transform trick as outlined here: https://www.fourkitchens.com/blog/article/fix-scrolling-performance-css-will-change-property

I've also used transform: translateZ(0) which from my understanding is a hacked way to create the same rendering trick that will-change does.

I've noticed a slight bit of difference with both of these. But ultimately the browser is not running silky smooth as I'd like it to be. Is this just a perennial issue that comes with using the fixed property? Or is there a way to make things nice and smooth?

Thanks,
