[solved]Transparent PIXI renderer on top of html image causing white border


Recommended Posts

I'm getting a side effect from having PIXI sprites over the top of an html image background. It seems like a white border or artifacts are created when transitioning between displaying the sprite and the image background. 

The z-index layout in html for the image and pixi: 

<!-- Background Html image -->
      position: absolute;
      z-index: 0;
      width: ${window.innerWidth}px;
      height: ${window.innerHeight}px;
      overflow: hidden;
    <img src={backgroundImg} />
<!-- PIXI Stage -->
      position: absolute;
      z-index: 2;
      transform: scale(${Math.min(window.innerWidth / 1920, window.innerHeight / 400)});
      transform-origin: top left;
      overflow: hidden;
      width: ${window.innerWidth}px;
      height: 600px;
    ref={element => {

Renderer settings:

const renderer = useRef(
   new PIXI.autoDetectRenderer({
        width: highwayWidth.current,
        height: highwayHeight.current,
        preserveDrawingBuffer: true,
        transparent: true,
        backgroundColor: 0xffffff,
        antialias: false,

Removing sprites from the stage reveals more of the background, but adds white border artifacts to the other sprites now too.


Removing the background added white artifacts to the next sprites transitioning to the html image:


Any advice on getting rid of this? Thanks for any help! ?
