Depth background showing in UI

Unity Engine

I’m displaying 3d models on UI using a raw image
For some reason when I switch the editor into android it shows the back ground color and isnt transparent.
Anyone know why. This is keeping me from launching my project into production.

Unity 2019.3.19

On Windows

On Android

It‘s not clear from just the screenshots how the UI is rendered.
Could be a problem with depth test. When Unity‘s screenspace UI is rendered the depth buffer is essentially uninitialized (but it depends…).
You could try to debug it in RenderDoc.

Thanks for the reply.
Screen space Overlay

Using a camera set to depth only looking at a 3d model
Then using a Render texture on a RawImage.
