Description of the bug

Turning off the monitor causes eww to crash.

Reproducing the issue

If eww is running and the monitor is turned off, when turned back on eww will have crashed.

From the logs:

 2024-08-16T08:13:31.265Z INFO  eww::app        > Closing gtk window bar

(eww:86616): GLib-GObject-CRITICAL **: 09:13:31.265: ../gobject/gsignal.c:2685: instance '0x564390eb3d80' has no handler with id '92'
 2024-08-16T08:13:31.265Z ERROR eww::error_handling_ctx > Failed to send success response from application thread

Caused by:

This seems unrelated to config, I’ve removed my config and replaced it with the barebones config below and still have the issue.

Running eww 0.6.0 on openSUSE.

Config:

(defwidget bar [] (music))
(defwindow bar
  :monitor 0
  :windowtype "dock"
  :exclusive true
  :geometry (geometry :x "0%"
                      :y "0%"
                      :width "90%"
                      :height "10px"
                      :anchor "top center")
  :reserve (struts :side "top" :distance "100px")
  (bar))

(defwidget music []
  (box :class "music"
       :orientation "h"
       :space-evenly false
       :halign "center"
    {"hello"}))

Expected behaviour

No response

Additional context

No response

can confirm. whenever I turn off my monitor the eww window crashes

[elkowar]

is this happening on wayland or on X11? Is it actually related to the monitor, or is it the entire computer going to sleep?
If wayland, we might need to do some explicit work to catch this sort of thing, Idk exactly how compositors deal with monitors vanishing and popping up

[cstruck]

oh sry, should have added that. Yeah, its wayland.

it crashes with

ah, its when I manually turn off my monitor either by unplugging or just hitting the poweroff button

I'll try to investigate within the next few days 👍🏻 Thanks for the report!
