Are you really sure that this has nothing to do with the CALayer? For me it
seems this is still blurry because it has been upscaled. Just the more gray
antialised font shading makes this less obvious.

I found this regarding CALayer and blurryness:

https://stackoverflow.com/questions/25746368/ios-drawing-in-calayers-drawincontext-is-either-pixelated-or-blurry-on-retina

It's for iOS, but maybe it applies for macOS too? At least it seems to be the
same problem. No idea if the proposed fix there can be applied on macOS
