Strange crash when using Filters


Recommended Posts

I add filter to containers

protected addStylesToContainer(container: Container): void {
	container.filters = [
    	new OutlineFilter(), // Everything work with this filter
        new DropShadowFilter(), // <-- Breaks here

But the error start to happen even if I call new DropShadowFilter() anywhere (!) in code, even without applying to object's filters property...

After some investigation I think it somehow related to masks. In other part of a code I create mask sprite from render texture:

const cont = new Container();
const tmpSprite = new Sprite(this.sprite.texture);

tmpSprite.filters = [new OutlineFilter(outlineSize, 0xffffff, 1, 1)];

const maskTex = RenderTexture.create({ width: tmpSprite.width, height: tmpSprite.height });
Game.renderer.renderer.render(cont, maskTex);

cont.destroy({ children: true });

this.maskSprite = new Sprite(maskTex);
this.maskSprite.name = 'Mask';

this.mask = this.maskSprite; // <--- THIS LINE CRASHES THE APP
