June 2025 monthly summary for Tencent/tgfx: Delivered performance-focused enhancements to the drawing pipeline and resolved a concurrency-related bug affecting task scheduling. Implemented rasterized cache-driven rendering for layer content, enabling more aggressive caching for filters and styles and reducing redundant draw calls. Fixed a DrawingManager issue where duplicate ResourceTasks with the same UniqueKey could fail to start, improving task reliability and stability. Expanded test coverage with new tests validating rasterized cache behavior across scenarios and adjustments to ResourceTask tests for accuracy. Overall impact: higher rendering throughput, lower CPU/GPU work, more predictable frame times, and stronger code quality through targeted tests and robust task management. Technologies/skills demonstrated: graphics caching strategies, concurrency-safe task management, test-driven validation, and performance-focused optimization.
