What problem does it solve?

It helps you analyze and improve ArkWeb rendering compositing behavior by evaluating compositor threading, layer management, GPU acceleration, and scrolling/animation performance.

Core Features & Use Cases

• Compositor architecture review: Assess BeginMainFrame → Commit → Activate → Draw flow, compositor frame submission, VSync alignment, and失帧 detection/recovery risks.
• Layer tree and performance risk analysis: Evaluate Layer Tree/Pending/Active triple-buffering, property trees (transform/clip/effect/scroll), and layer promotion/squashing leading to layer explosion.
• GPU and rasterization guidance: Verify GPU acceleration dependencies, software fallbacks, raster tile/bins scheduling, and raster cache hit strategy for memory/perf tradeoffs.
• Scrolling and animation compositing optimization: Provide guidance for compositor-driven/ threaded scrolling, scroll chaining, and compositor animations to reduce main-thread jank.
• Multi-thread synchronization risk checks: Identify risks around property tree modifications and commit-stage synchronization between main and compositor threads.

Quick Start

Ask the ArkWeb compositing expert to review your rendering/compositing requirement and return concerns, recommendations, and risks focused on layers, GPU acceleration, scroll/animation performance, texture memory, and multi-thread safety.
