This is the reason why I use parabola now.I read somewhere that "stable" is usually not, as many bugs are fixed constantly, and the quality of the GNU/Linux software is better everyday.
That convinced me and I am happy on parabola now :)I would suggest you to try it. After all you use I3wm and it seems like Parabola and i3wm are perfect match. Thats what I use after all.
