Running mate-settings-daemon with GTK_DEBUG=interactive freezes the desktop environment #257

Open heldplayer opened 5 years ago

heldplayer commented 5 years ago

Expected behaviour

mate-settings-daemon runs in the background, and a GTK Inspector window shows up for me to inspect the GTK objects used by the settings daemon.

Actual behaviour

The desktop environment freezes.

Steps to reproduce the behaviour

Alternative 1
  1. Append GTK_DEBUG=interactive to /etc/environment.
  2. Restart the system.
  3. Log in.
  4. mate-session will have spawned mate-settings-daemon and /usr/bin/ssh-agent /usr/bin/im-launch mate-session, but no other processes will have started under the session process effectively making the desktop useless.
    Alternative 2
  5. Log in to a MATE session.
  6. Send SIGSTOP to mate-session (to prevent it from instantly spawning a new mate-settings-daemon).
  7. Send SIGKILL to mate-settings-daemon.
  8. Start a new instance with GTK_DEBUG=interactive mate-settings-daemon.
  9. The desktop environment is now unresponsive.
  10. Using another shell (i.e. a virtual terminal) to kill the newly spawned mate-settings-daemon will restore responsiveness.

Alternatively if in step 4 you just run mate-settings-daemon, the desktop environment will remain responsive.

Why do I want to run mate-settings-daemon with the GTK Inspector?

I'm trying to write a theme and I'd like to be able to inspect the objects/nodes that are used for the overlays that render when using the volume buttons on my laptop.

That would be handy indeed, but GNOME themselves warn that GTK applications can be buggy with GtkInspector running.
