Jaggy edges when changing the new background colour

I have been playing around with the new background colour option but the issue i have is when i render out 2k or 4k i get visible jaggy edges around my model next to the background colour.

Hi @nigel

Sorry for any inconvenience caused. Could you confirm these few things for me?

  • Does the jagged edge issue occur only with a solid background color, or does it also happen when using an HDRI sky?
  • Are you rendering with Super Resolution (SR) enabled or disabled?
  • Does this happen across different projects, or only in a specific file?

Additionally, could you please share a screenshot of the rendered output showing the jagged edges around the model? Thank you, and I look forward to your update.

Hi ,
See comments below:

  • Does the jagged edge issue occur only with a solid background color, or does it also happen when using an HDRI sky? - Only when changing solid background colour with new feature

  • Are you rendering with Super Resolution (SR) enabled or disabled? I have tried with both settings and the issue still occurs

  • Does this happen across different projects, or only in a specific file? Yes across any project in which i change the background color
    Interestingly as a work around- if i render as a still from an animation there is no problem- the issue is purely with the render.
