During December 2024, the developer contributed to the felixonmars/treeland repository by implementing a dynamic blur effect for window surfaces. Leveraging C++, QML, and Qt, they integrated QtQuick.Effects.Blur into animation components and SurfaceContent, enabling per-surface blur control through new properties on animation items and the SurfaceWrapper. This work centralized post-processing logic, reducing fragmentation and improving visual consistency across the UI. The refactor not only enhanced the overall aesthetics but also established a scalable foundation for future visual enhancements. Their approach demonstrated a solid understanding of animation, UI development, and surface-centric rendering patterns within the Qt framework.
