Weird Pixel shape artifacts

Hi everyone,

I´d like to know if anyone has had any lighting issue regarding 4.24 version.

In my case i´m trying to build static lighting in my archviz project and get some weird pixel shape artifacts in shadow parts of my level.

It´s not related to lightmap resolution or lighting quality, both two parameters are set high enough to get a proper result in previous versions (4.21 - 4.22).

Lightmass settings are set quite high too (attached).

Thanks in advace.
Diego.
