Part of that 11+ minutes of the macOS build on GitHub Actions (which
starts from a clean machine) is downloading and installing the JDK and
other tools (gradle, etc), and cloning the repo. Also, incremental
builds are much faster after the first one. So even if you do a full
build once, subsequent builds for the debug-edit-build cycle is pretty
quick.
Phil might want to comment about the possibility of eliminating
sub-pixel (LCD) text entirely on macOS. If it does turn out to be
something worth doing, I note that macOS 10.13 is pretty old by now, so
that wouldn't be a compelling reason to hold off (as long as it doesn't
regress horribly).
As for Project Lanai, that isn't related to this issue. Lanai is an
implementation of the Java2D back end on Apple's Metal API (as an
alternative to OpenGL). See JEP 382 [1] for more information. We will
very likely do the same for FX starting in the not-too-distant future.

The builds for macOS are taking just over 11 minutes on GitHub.
To speed that up, I do my development in a project with only the
JavaFX Graphics module, linked below, and then use a guest machine to
do a full build for amd64 and armhf. Things go pretty quickly with the
help of 'rsync'. Not sure whether the same setup would help on macOS.

Do you know if the color fringes are being produced by the Core Text
rendering to a bitmap, and not the subsequent OpenGL phase?
No, I don't. I also don't know how the JavaFX code for macOS relates
to what's going on with the Lanai Project:

Regarding my suggestion of removing the sub-pixel rendering, it would
be good to check how many Macs out there are still running on macOS
10.13 High Sierra and earlier. Apple removed its sub-pixel rendering
and switched to grayscale anti-aliasing in macOS 10.14 Mojave.
