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.
