Comment:
Additional info:
* no bug if `wlroots` compiled with `logind` session backend
* no bug if I logout via `loginctl terminate-session $XDG_SESSION_ID` (which is also glitchless, unlike `swaymsg exit`)

I am not sure who is to blame here. `sway` doesn't appear to do anything session-related on exit, so `elogind` should handle everything. But that doesn't explain the different behavior between the two session backends.
