I wanted true native macOS “liquid glass” blur inside Qt 6, so this project wraps NSGlassEffectView (an undocumented API) and exposes it as a simple Qt widget. It falls back gracefully on Windows/Linux, so cross-platform apps still work normally.

This is mostly an exploration into how Apple achieves such a fast, low-latency blur compared to typical expensive multi-pass shader approaches. Open to discussion on cross-platform ways to approximate this effect or build a portable shader-based version.
