Child process does not stops

[nikto-b]

After killing waybar (for refreshing config, etc), child processes keeps working
I spent 10 minutes on killing custom script with loop for checking capslock state
Fix that plz :)
ArchLinux, waybar-git from AUR
Waybar v0.6.6-28-gfcf2d18 (May 30 2019, branch 'master')

I had looked into that and I have a "rough" version. But as I'm not fluent in C++ it's a bit harsh and still dies with a segfault some seconds later (which is not as bad a it has to be exited anyway ;))

BUT: As a quickfix for (at least bash-scripts) it should be possible to add set -euo pipefail in them and if one of the outputs fail it should exit.
Or use killall -g waybar which kills the process group.

I have encountered the same problem and can confirm processes do not exit. I was testing styles and 'reloaded' sway multiple times.

This issue is also present for me - perhaps this could be somehow handled from the mediaplayer.py script itself?
