Execute this code once and not three times in a row. This will save some overhead. Do it like so:

```js
const object = scene.getObjectByProperty( 'uuid', i );

object.geometry.dispose();
object.material.dispose();
scene.remove( object );

```

The order of the last three statements does actually not matter.

Does the memory leak disappear if you execute the following code after removing the cells?

```js
renderer.renderLists.dispose();

```
