Ask HN: Subpixel font rendering disabled on macOS Catalina?
Is anyone else experiencing this? Fonts look markedly worse on my external monitor after upgrading to Catalina. For example, here is a screenshot from Finder showing a clear lack of subpixel (RGB) anti-aliasing:

Subpixel rendering is still 'enabled' in the defaults system:
~ % defaults read -g CGFontRenderingFontSmoothingDisabled
0
- natenate19 7y agoSame behavior here with CGFontRenderingFontSmoothingDisabled set to 0 as well. Tried the old AppleFontSmoothing defaults hacks too, but those just make things look worse. Perhaps there is some new defaults string in Catalina that can be set? It seems like CGFontRenderingFontSmoothingDisabled set to 0 still has some effect on Catalina, but it's not subjectively the same result as was the case on Mojave.
- natenate19 7y agoHonestly things look subjectively better with CGFontRenderingFontSmoothingDisabled set to the default value of 1 on Catalina.
