I can confirm this issue, it happens after 0.7 release update.
my config file: https://pastebin.com/xFp2VfQz
Steps to reproduce:

  1. open 4 or more windows
  2. scroll on waybar like crazy
  3. waybar is frozen

I can confirm this. My custom scripts report a broken pipe when I do this.

looks like the ipc mutex is getting contention on two separate threads. one thread has it open and it is stuck on the workspace codex, which has it's own mutex it's locked on. the other is stuck waiting on the ipc mutex
