Backdrop Filter not working

[pronil-wedefineapps]

Type: Bug

if you apply backdrop-filter (css) to any element, the attribute seems to not work.

however if you add backdrop-filter: blur(20px) , you will still see some color smudges in the left and right side of the element where the filter being applied to. It started with the new version 1.98.0... previously it was working fine.
