iOS SDK: Glitchy image with transparency when calling deepAR.changeParameter("Quad", component: "MeshRenderer", parameter: "s_texColor", image: selectedImage)

SDK

Hello, we are using the iOS SDK and are noticing that if an image contains transparency (alpha channel AlphaPremultipliedLast) then it will sporadically display with a glitchy background.

See the glitch behind “Kelley Automotive Group” store logo.

Below that is the “storelogo” effect we are loading with each node/quad highlighted to show the settings/properties.

We are setting the image using:

deepAR.changeParameter("Quad", component: "MeshRenderer", parameter: "s_texColor", image: selectedImage)

We load the effect on screen load with:

deepAR.switchEffect(withSlot: "logos", path: path)

And we turn enabled hide (show the logo) with the following code:

deepAR.changeParameter("LogoNode", component: "", parameter: "enabled", boolValue: logoMode)

Any idea why these transparent images appear with a glitchy background? The glitchy pattern can differ as well.

Other notes:

  1. Already tried updating iOS SDK same issue
  2. Tried client-side code to change the alpha channel to preMultipliedFirst, mostly same issue
  3. Tried different timings, like waiting a few seconds after deepar is initialized to load the logo, same issue.
  4. Exhausted all Claude Opus and ChatGPT 4o recommended solutions, it seems to believe this is an issue with the DeepAR SDK

Any help would be appreciated.

Is there anyone that still works at DeepAR that can support a paying customer? Thank you
