There have been improvements recently, but it still has some of the worst text rendering of any editor on macOS, if you have a non-4K display plugged in. Rendering text is kind of a big deal!
A downside that comes with the territory of building the rendering pipeline from scratch is needing to work through the long tail of complex and tradeoff-heavy font rendering issues on different displays, operating systems, drivers, etc.
I know it's taking awhile to get through, but I agree it's important!
