Photoshop 21.0.3: 3D UV scaling results in incorrect rendering

When creating a 3D extrusion with an image used as the texture then the image appears correctly in the GPU  preview but, on ray traced rendering, the image appears twice - once correctly scaled and once incorrectly scaled.

To replicate :
1. Open an empty document (say 1024 x 1024 pixels)
2. Use place embedded to add an image as a smart object
3. With the smart object layer selected create a 3D extrusion.
This will create a 3D object with the image on the front surface

Press Render
The image will appear on the object  twice - once correctly scaled and as a superimposed image with incorrect scaling

The only workaround  (aside from using an old version of Photoshop) is to
a. Select the front material and Edit UV Properties to set scaling to 100% and offset to 0
then
b. Edit Texture and use transform to adjust the image to match the rescaled UV map

It's amazing how after a FOUR months, Adobe have done NOTHING at ALL to resolve this issue and it has started happening to me also. I now cannot get ANY work done and have no choice but to cancel my Adobe subscription. I see no point in throwing money into a software that is basically nothing more than a compilation of bugs and failures. Back to competitor software for me!

i have the same! shame of adobe... it seems nobody needs 3D from Adobe if no one complains. It is necessary to study normal 3D programs
