So following the setup described here: https://github.com/polybar/polybar/wiki#launching-the-bar-in-your-wms-bootstrap-routine
When I launch bspwm i don't see the bar at all. KIlling the bar and restarting it again after login seems to work.
The original bar does not respond to polybar-msg cmd quit either. I am not sure how to debug or what's causing the issues. The logs show no error at all before or after restarting.
See also #2697
The issue is that polybar waits for a signal from its callback function but if the signal is sent before pa_threaded_mainloop_wait is called in the module constructor, the signal is lost and the module (and thus polybar) waits forever (see 6d7a7c0).
