附加信息

The issue arises because all the tile layers are added to the map, and each layer fetches its tiles and retains them in memory indefinitely. Below is an example of the same map where the layers are removed instead of simply being hidden. This approach prevents memory issues by releasing the tiles when the layer is removed. Refer to this link https://codepen.io/U_B_U/pen/NPKREQm?editors=1000 for more information. With that said, the memory usage are further improved. If a layer remains invisible for a certain period, the layer view must automatically purge the tiles from memory, freeing up resources and optimizing performance.
