I didn't noticed the pattern with DynamicDraw usage in Attributes.js. This is actually the correct PR. /cc @sunag

Thanks for that.

Also my attempt did unveil an issue which is the forwarding of version update for non-DynamicUsage draw pattern in InstancedMesh.
Consequently we should update InstanceNode with:

update( /*frame*/ ) {

	if ( this.instanceMesh.instanceMatrix.usage !== DynamicDrawUsage && this.instanceMesh.instanceMatrix.version !== this.buffer.version ) {

		this.buffer.version = this.instanceMesh.instanceMatrix.version;

	}

	if ( this.instanceMesh.instanceColor && this.instanceMesh.instanceColor.usage !== DynamicDrawUsage && this.instanceMesh.instanceColor.version !== this.bufferColor.version ) {

		this.bufferColor.version = this.instanceMesh.instanceColor.version;

	}

}
