I dont't know whether this is related, but I also have weird crashes every few days. There's a core dump attached: polybar.dump.gz Config;==========================================================

Alright, I took a look at this core dump myself with gdb. The reason for this crash is a data race between two threads interacting with the same data structure. (Why needs a bar 16 threads?) The problem is Unfortunately, the So the OP uses bspwm instead of i3 which makes my crash not directly related to the original issue. But I would also assume that data races might be the key to find the cause for that crash. |

Describe the issue
Polybar v.3.4.3 crashes at least once a day on arch with bspwm. I don't know why it crashes and can't reproduce, I didn't find with what it can be related.
After a crash I get this message at journalctl :
`Process 1196 (polybar) of user 1000 dumped core.
Was it working before?
No, always crashed. I even reinstalled arch.
To Reproduce
