bug: glaze crashes due to ipc

[Dimfred]

Glaze crashes when I am subscribed to focus_changed.

How to replicate:

subscribe -e focus_changed

Tab a little bit from left to right => see crash after a ~15seconds.

[theSoberSobber]

how are you subscribing to the event? where do you run commands with the glazeWM executable? like the subscribe -e focus_changed command?

[Dimfred]

No I was running them in a python server. The server was running inside wsl.

The code was simple, basically send the subscribe message subscribe -e focus_changed, the while True: await ws.recv().

Used more or less this as an example:
