alacritty: Regression in font rendering in 0.4.3 vs 0.4.2

System:

OS: macOS 10.14.6

Settings:

• use_thin_strokes: false
• defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO

There is already some discussion of this in the comments of #3804, but I’m opening a separate issue specifically for this issue.

With use_thin_strokes: false set, font rendering appears to be worse in 0.4.3 than it was in 0.4.2:

0.4.2:

0.4.3:

The change is quite subtle, but it definitely looks less smooth in 0.4.3. For what it’s worth, this (0.4.3) looks similar to other font rendering on my system when defaults write -g CGFontRenderingFontSmoothingDisabled -bool NO is not set (i.e. without subpixel anti-aliasing).
