This article is about a machine running macOS. Nothing to do with Cleartype in here at all.

Didn't MacOS remove any form of subpixel hinting like 6 OS versions ago?

The OP seems to have a problem not only with fonts but also with straight lines in CAD.

OP is me, and yeah, AFAIK they did.

It's a problem with how this subpixel problem aligns with my use (mostly static content with high contrast edges) at the display scaling I'm using.

It just doesn't work for me, so until I can get a more traditional pixel pattern OLED at a price I'm willing to pay I'll just go back to LCD.
