Tbh I'm not even sure what the issue is here. I have a personal M1 macbook and a work M4 and a 4k display. I don't see any issues or differences between them on my display. The M4 seems to be outputting a 4k image just fine.
The article could just be AI slop since it just contains hyper in depth debugging without articulating what the problem is.
Right, I just went though all of the scale options on my M4 with 4k monitor and none of them rendered blurry. Might be a very situational bug. Doesn't seem as widespread as the title makes out to be.
