CSS Backdrop FIlter Behaviour about dom-overlays HOT 2 CLOSED

Yes, there is specified behavior, see https://immersive-web.github.io/dom-overlays/#css-pseudo-class

The overlay element is a backdrop root.

NOTE: Backdrop filter effects on the DOM overlay element or its descendants do not modify the AR camera image (if applicable) or the rendered content drawn to the immersive session’s XRWebGLLayer.

While it would indeed be cool if this could work, it would be a challenge to implement. The current smartphone AR implementation composes the camera data and GL drawn content separately from the DOM content, so the needed source pixel data for filtering isn't currently available in the DOM compositor. While this would potentially be fixable for smartphone AR, it's even more difficult for a see-through AR headset. That may not have a color camera image to use as input for compositing, and it would be tricky to do this correctly for each eye, especially if it's an additive-only display that can't darken the camera image.
