Why blur effect disappears in slick slider?

Question

css

I use CSS for slick slider slides , but while flipping the slides, the blur effect disappears for a second, and then reappears. Moreover, if you drag the slides with the mouse, then blur disappears at the moment when I release the mouse button. What could be the problem? How to fix it? Example: https://codepen.io/maxbeat/pen/abNBrexbackdrop-filter: blur(10px)

Answer 1

Not in defense of slick, but perhaps the property itself is still crookedly working. is sort of in the status of a draft in the specification.
For example, nothing is lost with the property.
filter: blur(10px);
