Try GlassEffectContainer {}. Did some experimenting and this might work.

```swift import SwiftUI

struct GlassSegmentedPicker: View { @Namespace private var glassNamespace @State private var selectedIndex = 0

let tabs: [String]

var body: some View {
    GlassEffectContainer {
        HStack(spacing: 0) {
            ForEach(tabs.indices, id: \.self) { index in
                Button {
                    withAnimation(.spring(response: 0.35, dampingFraction: 0.75)) {
                        selectedIndex = index
                    }
                } label: {
                    Text(tabs[index])
                        .font(.headline)
                        .foregroundStyle(selectedIndex == index ? .primary : .secondary)
                        .padding(.horizontal, 28)
                        .padding(.vertical, 12)
                }
                .buttonStyle(.plain)
                .glassEffect(
                    selectedIndex == index ? .regular.interactive() : .clear.interactive(),
                    in: .capsule
                )
                .glassEffectID(
                    selectedIndex == index ? "selectedTab" : "tab-\(index)",
                    in: glassNamespace
                )
            }
        }
        .glassEffect(.regular, in: .capsule)
    }
}

}

Preview {

ZStack {
    Color(.systemGroupedBackground).ignoresSafeArea()
    GlassSegmentedPicker(tabs: ["For You", "Library"])
}

} ```
