During September 2025, Mickey Miao focused on maintaining and improving the vector graphics module in the lvgl/lvgl repository. He addressed a critical bug in the image stride calculation for fill patterns, which previously led to rendering defects in UI components. Using C and leveraging his expertise in embedded systems and graphics rendering, Mickey implemented a fix that ensures correct image stride handling and added automated tests to validate PNG rendering. This work enhanced the reliability and visual fidelity of LVGL’s vector module, reducing the risk of corrupted visuals and supporting long-term maintainability for applications built on the platform.
