What Happened?

RecApp-2024-01-23-22:32:18.webm

Another time it crashed instead of breaking but I don't know how to reproduce that.

Steps to Reproduce

  1. Compile latest master
  2. Have two monitors connected
  3. Toggle mirror display on and off again

Expected Behavior

Don't break

OS Version

7.x (Horus)

Software Version

Compiled from git

Log Output

(io.elementary.switchboard:54553): GLib-GObject-WARNING **: 22:32:25.452: ../../../gobject/gsignal.c:2765: instance '0x5635e3ee81b0' has no handler with id '2273'

(io.elementary.switchboard:54553): GLib-GObject-WARNING **: 22:32:26.382: ../../../gobject/gsignal.c:2765: instance '0x5635e3ee83a0' has no handler with id '2687'

Every time the switch is toggled one of these gets emitted.

The time it crashed I got the same but also

(io.elementary.switchboard:53610): Gtk-CRITICAL **: 22:28:19.787: gtk_widget_destroy: assertion 'GTK_IS_WIDGET (widget)' failed

followed by a segfault. I don't know how to reproduce the crash though.

Hardware Info

No response
