glassEffect() in SwiftUI always renders as white – even with latest Beta 2 on macOS 15

Hi everyone,

I’m having trouble getting the new glassEffect() modifier to render correctly in SwiftUI.

No matter what I try, it just appears as a solid white background (instead of translucent glass). This happens both in Beta 1 and Beta 2.

My setup: • Mac mini (M4 chip) • macOS 15 Beta 2 (Tahoe) • Xcode 16 Beta 2 • Samsung Odyssey G9 57” monitor (super ultrawide) • Using Preview in SwiftUI (not the Simulator)

Even when I use Apple’s default demo code like:

Text("Hello World") .padding() .glassEffect()
