What you did

.slider__item {
  height: 200px;
  margin: 10px;
  display: flex;
  align-items: center;
  justify-content: center;
  font: 24px arial;
  background: rgba(255,255,255,0.5);
  backdrop-filter: blur(10px);
}

Expected Behavior

I would like my slides to have the glassmorphism effect, so the slider would blurry the background image on the page.

Actual Behavior

the backdrop-filter goes away right after I release the mouse button, and comes back after the slider finishes moving. If I use other effect, like coverflow, it looses even the rotation and depth effect while moving.
