UE 5.3 groom problem, especially the shadow area

After upgrading to version 5.3 ,
A ‘horizontal’ line occurs in the shadow of the “groom”.
Have any of you experienced the same phenomenon as mine?
And if you have a solution, I sincerely ask you to share it.

Hello, I have the same issue. Did you find a solution for that?

There was indeed an issue we discovered only recently and got fixed in our mainline. Unfortenuately this fix will only be part of 5.5. The fix is only about shader, so you can technically just grab the change, and restart the engine. The fix was checked in CL 33838275 in our mainline.

Thank you for letting us know! In engine scalability settings, I switched only the shader quality from cinematic to epic, and it saved my render.

What changes are to be done in shaders to slove this issue

was the issue solved ?
