Flicker on Architecural parallel lines

Hello and I really thank you for taking time to answer.

Apparently, there are no “out of bounds pixels” error
I tried to adjust some parameters or extend the bound size for “occlusion culling” , but nothing changed

So, I’ve started a new project to test the problem

I just create a new project with the preset for architecture, enginering and Construction named “Archvis” with raytracing enabled

I drop the cube preset in the scene, duplicate the shape and the flickering artefact are present on the meshs and there is also problems on the shadows

Maybe, it has something with “BaseScalability.ini” or “DefaultEngine.ini” files?

I also tried to adjust the temporal motion blur that should attenuate the problem, but it doesn’t seems to work for this
