the immutable “what to draw” package for this frame.

A PaintArtifact is the product of Blink painting: a DisplayItemList plus an ordered vector of PaintChunks. It is immutable post‑creation and designed for reuse (granular caching at item/chunk level) across frames. (Chromium Git Repositories)

Notable API/fields

  • const DisplayItemList& GetDisplayItemList() const;

  • const PaintChunks& GetPaintChunks() const; — the input that compositing consumes. (Chromium Git Repositories)

Hands off to: PaintArtifactCompositor.
