...if only the scroll offset is updated. Currently, on any document with a large amount of content, the process of building a display list is often more expensive than its rasterization. This is because the amount of work required to build a display list is proportional to the size of the paintable tree, whereas rasterization only occurs for the portion visible in the viewport. This change is the first step toward improving this process by caching the display list across repaints when neither style nor layout requires invalidation. This means that repainting while scrolling becomes significantly less expensive, as we only need to reapply the scroll offsets to the existing display list. The performance improvement is especially visible on pages like https://ziglang.org/documentation/master/ or https://www.w3.org/TR/css-grid-2/ |

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
- LibArchive: Archive file format support
- LibUnicode: Unicode and locale support
- LibAudio, 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.
