Whether stroke color is set or unset is neither a bug nor a feature, it 
is a compromise.

Try experimenting with the antialiasing setting.

There have always been problems along these lines, because no 
combination of edgewidth, stroking on or off, and antialiasing on or off 
works without artifacts on all backends and for all values of alpha.
