Exactly the same for me! Got bash for Windows up and running with i3 on vcsrt. Ff is running in i3 and it is relatively smooth (I have a beefy specs). Almost all my settings have been ported. However, emacs is struggling because of some weird issue not going fullscreen and there's lots of issues with other execs (GUI in particular) because of dbus (I think)... There's also a super annoying issue with the windows button which I normally use as meta key for i3....
