🛠️ Fixes

Gray Outline (Halo)

A long-standing issue causing gray/dark outlines (halo artifacts) around subjects has been resolved.

Old (with outline)

New (without outline)

Cause

• Inconsistent handling of premultiplied and straight alpha during compositing.
• Resulted in visible edge artifacts, especially on light backgrounds.

Fix

• Reworked the compositing pipeline to ensure consistent alpha handling.
• Properly reconciles RGB and transparency before blending.
• Uses a mathematically correct compositing method.
