We are seeing these blocky artifacts in extreme dept-of-field situations. The artifacts show up when we’re using TAA. Are there any ‘tricks of the trade’ to work around these? This is a picture of some blurry plant leaves that are very close to the camera.

Going to link you to this article. It’s the same issue, I fixed this same problem in my project by disabling alpha output just as shown in the project settings. I hope this helps you out.
