From FontForge, I could find no technical problems with either of the glyphs (superior figures 1 and 4), and there is no problem with the corresponding inferior figures, which are simply translates of the superior figures. (I have "Use LCD smoothing when available" turned off in System Preferences/General, as I have seen similar problems show up when that is turned on.)

Howdy,

I just rebuilt the pdf file from the source and am not having a problem with viewing it in Preview or TeXShop. I do have "Use LCD smoothing when available" checked and everything looks nice and sharp even on my non-Retina display. Maybe things have changed as far as that preference option is concerned.

I will say that Preview had a terrible time loading the original version of the pdf file which I got using `texdoc cormorantgaramond`.

There is definitely a problem with PDFKit in macOS 10.12.4 and not only with using tikz+pstricks and compiling with pdflatex. I compiled a simple file and it took a long time to display in TeXShop's preview window; subsequent compiles displayed quickly. I'm wondering if there is some caching going on when a new font that's unknown to the system is first displayed.

Good Luck,
