But GTK4 text rendering is blurry

Mac's generally have a HiDPI screen so they shouldn't be affected by the issue you're parroting.

That said, I already wrote GLyphy integration for GTK 4 and it may land before 4.8. It can significantly improve font rendering quality by drawing the glyphs on the GPU rather than from CPU drawings uploaded into an atlas which is pixel boundary bound.

It's very unclear to me wether hidpi makes the non-subpixel rendering bearable or wether the rendering would still be better if it exploited subpixel antialiasing on 4K, it's just that the perceived difference is smaller and good enough. I don't know.

All text rendering on recent macos versions is blurry in the same way as GTK4.

two wrongs don't make a right. I'm pretty sure google chrome or firefox rendering are unaffected.
