Informations supplémentaires

This is working as designed. In the current setup, the app listens to the pointer-move event without using debounce and runs hitTest on all layers. The logic triggered by the pointer-move event is competing with layer queries for resources, which can cause performance issues. Here are some recommended changes: 1. Add debounce to the pointer-move event to limit how often the logic runs. 2. Run hitTest only on the layer of interest rather than all layers. The app has been updated to apply these changes, resulting in smoother performance and less resource competition: https://codepen.io/U_B_U/pen/gbPJqPo?editors=1000 Updates shall be made to the sample that this app uses to reflect the recommended workflow so future implementations follow best practices.
