Worked on stabilizing the DevTools UI for the Tencent/Hippy project by addressing a persistent DOM tree flicker on the Animation page. Using C++ and front-end development skills, implemented a targeted fix that comments out the handling of the kDomTreeUpdated event, thereby preventing unnecessary full DOM redraws in the debug frontend. This approach improved the stability and usability of the animation debugging experience while reducing iteration cycles for UI changes. The solution was documented with a plan to migrate toward property-level updates in future iterations, reflecting a thoughtful approach to incremental optimization and maintainability within the project’s debugging infrastructure.
