The decoded-frame Skia image cache is useful for display-list rasterization because decoded image resources can be replayed over many frames. The cache lets that path reuse SkImage wrappers and GPU-backed copies instead of rebuilding them whenever the same resource is painted. For canvas, commands are consumed into one backing surface and decoded frames are already held by the command or paint style for the draw. A per-painter cache does not match that usage model, and can keep decoded frames and Skia images alive after the draw has consumed them. This removes the cache from PainterSkia and drops the now-unused pruning hook from CanvasCommandPlayer. With the cache gone, PainterSkia can hold its painting surface directly instead of allocating a private Impl. DisplayListPlayerSkia keeps owning the cache, so display-list rasterization keeps the SkImage reuse behavior. |

Ladybird
Ladybird is a truly independent web browser, using a novel engine based on web standards.
Important
Ladybird is in a pre-alpha state, and only suitable for use by developers
Features
We aim to build a complete, usable browser for the modern web.
Ladybird uses a multi-process architecture with a main UI process, several WebContent renderer processes, an ImageDecoder process, and a RequestServer process.
Image decoding and network connections are done out of process to be more robust against malicious content. Each tab has its own renderer process, which is sandboxed from the rest of the system.
At the moment, many core library support components are inherited from SerenityOS:
- LibWeb: Web rendering engine
- LibJS: JavaScript engine
- LibWasm: WebAssembly implementation
- LibCrypto/LibTLS: Cryptography primitives and Transport Layer Security
- LibHTTP: HTTP/1.1 client
- LibGfx: 2D Graphics Library, Image Decoding and Rendering
- LibUnicode: Unicode and locale support
- LibMedia: Audio and video playback
- LibCore: Event loop, OS abstraction layer
- LibIPC: Inter-process communication
How do I build and run this?
See build instructions for information on how to build Ladybird.
Ladybird runs on Linux, macOS, Windows (with WSL2), and many other *Nixes.
How do I read the documentation?
Code-related documentation can be found in the documentation folder.
