Summary
Fix the macOS pet window rendering with an opaque white background by enabling Tauri's macOS private API support for transparent windows.
Root Cause
The pet window is already configured with
transparent: true, and the pet spritesheet contains transparency. On macOS, Tauri also requiresapp.macOSPrivateApiplus the matchingmacos-private-apiCargo feature for transparent windows. Without those settings, the WebView is composited as an opaque white rectangle.Changes
app.macOSPrivateApiinsrc-tauri/tauri.conf.json.macos-private-apifeature on thetauridependency insrc-tauri/Cargo.toml.A/B Test
The screenshots below are composited on a checkerboard background so the transparent pixels are visually obvious.
Before:
transparent: truewithoutmacOSPrivateApiRuntime output includes Tauri's warning that
macos-private-apiis not enabled. Window capture result:alphaMin=255, transparent pixels0/402560, corners are opaque white[255,255,255,255].After:
macOSPrivateApiandmacos-private-apienabledWindow capture result:
alphaMin=0, transparent pixels305811/402560, all four corners are transparent[0,0,0,0].Validation
