Enum WindowBackgroundMaterial 

#[repr(C)]
pub enum WindowBackgroundMaterial {
    Opaque = 0,
    Transparent = 1,
    Sidebar = 2,
    Menu = 3,
    HUD = 4,
    Titlebar = 5,
    MicaAlt = 6,
}

Compositor blur/transparency effects for window background.

Anything but Opaque gives the window PER-PIXEL alpha on the CPU path: the frame is cleared to transparent and whatever the content leaves at alpha 0 shows the desktop through (a border-radius on the body makes real rounded corners; a clip mask on the body makes any shape). The window’s INPUT shape follows that alpha as well - clicks on fully transparent pixels fall through to whatever is behind, on every backend (macOS does this by itself for a non-opaque window; X11 gets an XShape, Wayland an input region, Windows a window region). This is partial (per-pixel) transparency, not whole-window opacity; X11 without an ARGB visual falls back to _NET_WM_WINDOW_OPACITY, which is whole-window.
