By removing _transparentPrimitiveInfo in the dispose function, I solved this problem. RenderablePrim2D.prototype.dispose = function () { if (!_super.prototype.dispose.call(this)) { return false; } if (this._modelRenderInstanceID) { this._modelRenderCache.removeInstanceData(this._modelRenderInstanceID); this._modelRenderInstanceID = null; } if (this._modelRenderCache) { this._modelRenderCache.dispose(); this._modelRenderCache = null; } if (this._transparentPrimitiveInfo) { this.renderGroup._renderableData.removeTransparentPrimitiveInfo(this._transparentPrimitiveInfo); this._transparentPrimitiveInfo = null; } if (this._instanceDataParts) { this._instanceDataParts.forEach(function (p) { p.freeElements(); }); this._instanceDataParts = null; } return true; };
