Many people (Myself included) like to have their chrome windows slightly transparent while some elements such as the urlbar with backdrop filter. The issue is that backdrop filter simply doesn't work right there because when WR detects there's no solid backgrounds behind the window, it just doesn't blur at all.

Reproduced on Linux (Debian/Ubuntu/Wayland) with Firefox 150.0.x. Same symptom: backdrop-filter: blur() on #nav-bar and .urlbarView is correctly applied (verified via Browser Toolbox → Computed styles with "Browser styles" enabled, value blur(25px) saturate(150%) resolves correctly on the element) but the compositor renders no blur. Was working fine in Firefox 149.
Cross-platform confirmation: other users on Windows reported the same in r/FirefoxCSS thread "Custom effects broken after 150.0" (https://www.reddit.com/r/FirefoxCSS/comments/1svl85i/), so the regression / missing feature is not OS-specific.
Thanks for working on this!
