bug#31904: 27.0.50; Emacs doesn't render text/modeline Mac OSX 10.14 Mojave

[address@hidden]

Emacs from the master branch compiles on Mac OS 10.14 (Developer Beta 1
and 2) just fine, but when I run the resulting Emacs.app, none of the
text or even the mode-line appears in the frame.

- If I "select" the text in the scratch buffer, I see nothing, but I can
  then paste it into another application just fine.

- If I type something in the scratch buffer, I can't see it. I can
  select it (but not see the region), copy it, and paste it into another
  application and see the text I've typed.

- The mode-line isn't rendered, either.

- Running Emacs.app/Contents/MacOS/Emacs -nw in a terminal window works
  fine.
  
The application seems to be working in all particulars except the text
is invisible (not the same color as the background, just not there).
