I have created a scene using THREEJS that loads GLTF files and image-format tile maps. When I repeatedly destroy and rebuild the scene(ensuring that each destruction removes DOM nodes and all relevant THREEJS objects), I notice that the memory keeps increasing in the Safari browser, but the same code performs normally in the Chrome browser. I have ensured that I properly dispose of all relevant resources when destroying the scene.

The following is the core code of my destruction function:

```javascript
static disposeObject(object, withMaterial: boolean = true){
        const self = this;
        const disposeMaterial = (material: Material) => {
            Object.getOwnPropertyNames(material).forEach((property: string) => {
                const materialProperty = (material)[property];
                if (materialProperty !== undefined && materialProperty instanceof Texture) {
                    const texture = materialProperty;
                    const image = texture.source.data;
                    if (image instanceof ImageBitmap) {
                        console.log('dispose imagebtmap');
                        image.close();
                    }else{
                        console.log('dispose image');
                        texture.image = null;
                    }
                    texture.dispose();
                }
            });
            material.dispose();
        };

        if (object instanceof Object3D) {
            if (object.parent) {
                object.parent.remove(object);
                object.parent = null;
            }
        }

        if(object.children&&object.children.length>0){
            for (let i = object.children.length -1; i >=0 ; i--) {
                this.disposeObject(object.children[i]);
            }
        }
        object.children.length = 0;
        object.children = null;

        if (object.geometry !== undefined) {
            object.geometry.dispose();
        }

        if (object.geometries !== undefined) {
            for (const geometry of object.geometries) {
                for (const key in geometry.attributes) {
                    geometry.deleteAttribute(key);
                }
                geometry.setIndex([]);
                geometry.dispose();
            }
        }

        if (object.material !== undefined && withMaterial ) {
            if (object.material instanceof Array) {
                object.material.forEach((material: Material | undefined) => {
                    if (material !== undefined) {
                        disposeMaterial(material);
                    }
                });
            } else {
                disposeMaterial(object.material);
            }
        }
        for(let key in object.userData){
            delete object.userData[key];
        }
        object.userData = {};
        object = undefined;
    };

```

THREEJS Version: r138  
Google Chrome Version: 119.0.6045.200  
Safari Version: 17.0(19616.1.27.211.1)  
Is there anyone who can give me some advice? Thanks！！！

Can you link the bug you posted on Safari’s bug report channel?

This is a discussion about the same problem with consideration of the condition in `GLTFLoader` regarding Safari version 17 and the fact that today Safari 18 is used.

There is also a link to JSFiddle with an example that demonstrates the memory leak in less than 50 lines of code.

Hello, are there any news about this? We have the same exact problem on Safari.

Thanks.
