Floating menus hover over undimmed content (no backdrop scrim like dialogs), so the frosted .glass (78%) let the content bleed through and hurt readability. Add a near-opaque .glass-menu (surface 92%, keeps blur) and use it for the account, language, notification and add-to-playlist popovers. Dialogs/chrome keep the frostier .glass (they sit over a dark scrim / the ambient bg). perf-mode disables its blur too.
