I'm using zsh/prezto with syntax-highlighting plugin. When I use the arrow keys to navigate within the terminal command, the cursor disappears in the embedded terminal and blinks/flashes every ~second.
Here is an example (gif):

It does not happen within Terminal.app or iterm. If I disable syntax-highlighting within .zpreztorc it works like expected. =(
I disabled the cursor highlighter and now it works!
.zpreztorc
zstyle ':prezto:module:syntax-highlighting' highlighters \
   'main' \
   'brackets' \
   'pattern' \
   'line' \
   'cursor' \ <-- removed
   'root'
