@Bouh does it render any texture at all? I feel like we've broken the texture rendering somehow, either way I'll look at it :+1:

No image works.

Let me know @HarsimranVirk if you can debug this/need help - probably a mistake that caused a regression. We also have an issue of some shader issues on iOS/some Android mobile devices, I'll also try to help on this maybe we're using something not supported by some GPUs.

If the renderTexture from the layer is missing the rest of the code bug. Even with the return:

gdjs.LayerPixiRenderer.prototype._updateRenderTexture = function () {
  if (!this._pixiRenderer) return;

Bug report by an user, not reproductible...

Seems pretty weird to me, renderTexture can't be undefined (although it can always be null, since that's the default framebuffer).

True, I couldn't reproduce, might be something very specific to pixi I guess.
