WebRender’s 28th newsletter is here, and as requested, today’s little story is about picture caching. It’s a complex topic so I had to simplify a lot here. Moved to a separate post now.

- Kats restored a specific dragging behavior for the scroll thumb on Windows.
- Kvark improved the performance of solid line decorations by moving them to the opaque pass.
- Matt improved text selection performance.
- Emilio optimized inset clip paths into using complex clip regions instead of blob images.
- Glenn removed primitive indices from chasing .
- Glenn introduced a picture traversal pass .
- Glenn introduced primitive clustering.
- Glenn stored picture indices in instances.
- Nical fixed a bug with srgb/linear color conversion in WebRender.
