Reproducing steps:
1. emacs -Q
2. M-x blink-cursor-mode
3. menu-->Options-->Set default font-->choose a bigger size
4. M-x load-theme light-blue
5. switch to other app and then back to Emacs
6. The color of the cursor doesn't restore.
7. After a mouse click in the emacs frame, the cursor color restores.

Interesting that you both appear to be using 10.13. I made some changes
that affect 10.13 rendering on the master branch recently. Can one of
you please check whether you still see this on master?

I can no longer reproduce this on current master.  Since there has
been no other reply within 3 weeks, I'm going to assume this is fixed
and close this bug.  If anyone is still seeing this, please report
back and we can reopen the bug.  Thanks.
