Maybe some anti-aliasing issue?
For me, dots are also quite small and some of them are barely visible, while others look quite normal.

When I played around with the grid dots on OS X in legacy canvas I also had a hard time to find a configuration where dots are visible both on (HiDPI) retina and normal displays (on OS X also legacy canvas is anti-aliased).
