4.0 denoiser generates extra border

[J.C]

If you enable alpha channel, Render layers and the denoiser the denoised layer gets extra border around image.

Could you please send us the scene for investigation?

Sure, here it is.

Thanks for the scene. We will look into it.

Thank you for the scene. That was caused by the fact that the denoiser extends the alpha channel. We are trying to improve the denoised alpha channel, but in the meantime use the not denoised alpha channel instead which fixes this and other issues. This change has been included in version 4 RC5 already.

One thing I have noticed though is that if you enable keep environment and render layers, the main pass shows a black background while the denoised pass shows the environment, which it shouldn't. We will fix that.

This happened to me to with RC4 but it wasn't in the saved version for some reason, it just showed up in the Live Viewer, but not in the final saved render. I did an animation with alpha channel and keep environment selected.
