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.

 ![Screenshot 2025-06-11 at 17.46.58](https://europe1.discourse-cdn.com/flex017/uploads/deepar/original/2X/2/2783404782d9a55026629944a7c351b4382fe97f.jpeg)

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:

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

```

We load the effect on screen load with:

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

```

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

```auto
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.

Thanks,

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

Exactly, I’ve been trying to reach them for a month, not even a single reply, did you manage to get an answer from them somewhere else?

No, I’m extremely concerned that a future iOS release bricks the entire SDK and there is no one to resolve the issue. We are taking this as indication to start finding other SDKs.
