Module material 

material — the material-glass float: wraps a popover/dialog card so its ENTIRE subtree paints inside one scene layer (a single draw order).

The single layer order is the point: with per-primitive bounds-tree ordering, a hover repaint elsewhere can reassign the card’s quads relative to siblings — inside one layer the card’s stacking is structural.

The blur is painted first, structurally under the content: inside one layer the order is blur, then shadow, tint, border, rows, text. It needs Window::paint_backdrop_blur from our gpui fork (macOS Metal only); elsewhere the primitive is ignored and the glass reads as the theme’s translucent tint over the OS window blur.

Glass::glass_effect is the liquid surface: a bevel at the rim that refracts the backdrop, and a fill of its own.

Constants

MENU_BLUR

Backdrop-blur sigma for floating menu/dialog glass — the reference .glass-surface runs blur(44px), and the Theme::glass_overlay tint is thin enough that a 16px blur leaves backdrop detail ghosting through rows.

PANEL_BLUR

Backdrop-blur sigma for a small floating panel — a meter, a HUD. A sigma is only frost while the box is wide enough to show what it softened; at a quarter of the box’s width the backdrop resolves to one flat tone.

Traits

Glass

The backdrop surfaces, on any element carrying a corner radius.

Functions

layered

Paint child in its own scene layer, giving it a fresh draw order above everything painted so far in the enclosing layer.

lensed

Whether Glass::glass_effect will actually refract here, rather than falling back to the flat backdrop tint. The primitive is macOS Metal’s, and an opaque appearance has nothing behind it to lens.

material

Frost a card whose rounding the caller states — the shape the popover layers need, where the card arrives already erased to an AnyElement and its radius belongs to the surface kind. Backdrop-blurred on glass, pass-through on opaque platforms.
