The artifact is there before 5.2 but since the ray traced shadow denoiser denoises on the sqr() space previously, that artifact is less noticeable. After bug fix in 5.2, we get better shadows but also reveals this artifact. Need to improve the ray traced shadow denoiser to reduce this artifacts.
Occurs in both 5.3.1 and 5.3.2, this is not a regression. Tested in //UE5/Release-5.3 @ CL29314046
Results: Artifacts can be seen from the edge of the cube overlapping with the shadow
Expected: No artifacts occur on the edge of the cube
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-200307 in the post.
