If you're using I-Bus, then that's the Unicode code-point input panel.
You can disable it by running:

  gsettings set org.freedesktop.ibus.panel.emoji unicode-hotkey []

Or removing the "Unicode code point" entry in the Emoji tab of
ibus-setup.

The reason C-g does not work and Emacs appears to be unresponsive is
that the input method filters out all keypresses and sends them to the
panel, and switching to another window serves to dismiss that panel.

That's expected, since those combinations are handled by the GTK input
method machinery.

Thanks.
