PROFILE

Liu Heng

Worked on core components of the linuxdeepin desktop environment, focusing on UI reliability, stability, and user experience improvements across dde-shell, dde-tray-loader, and dde-launchpad. Addressed popup lifecycle issues by introducing centralized event handling and memory safeguards, using C++ and QML within the Qt framework. Enhanced asynchronous DBus workflows to improve responsiveness and prevent blocking, while refining scaling protocols and icon sizing for visual consistency. Fixed compositor-related artifacts in dde-tray-loader to support headless or lightweight setups. Maintained clear release management practices by documenting changes and version bumps, ensuring maintainability and transparency for downstream users and future development cycles.
