Transparency not working

After investigating further and consulting with Apple, we determined that the volume size issue comes from the Display → Appearance → Window Zoom setting. If you change it from the default “Large,” you get a volume that doesn’t match the size requested in PolySpatial (e.g., on “Small,” you get a volume of about 75% the size). We’re still trying to determine whether this is expected behavior on visionOS, and thus whether we should be scaling our content to match the volume size.
