Backdrop-filter blur not working when moving

Hi!

I want to use glassmorphism on some slider cards. It works well with backdrop-filter: blur(10px), but when I activate the slider, the effect disappears…

It’s on the 6th section “Ils chantent nos louanges” (testimonies) of this page: https://budees-by-pablo.webflow.io/

Any clue?

Thanks!
