configure.ac suggests otherwise:

  pgtk )
    term_header=pgtkterm.h
    with_gtk3=yes
    USE_X_TOOLKIT=none
  ;;

As does the GTK3 seen in the system-configuration-features part of my
signature in the OP.

I don't use a desktop environment, and I'm not really familiar with GTK,
but here's my $XDG_CONFIG_HOME/gtk-3.0/settings.ini:

  [Settings]
  gtk-font-name                     = DejaVu Sans 10
  gtk-icon-theme-name               = Adwaita
  gtk-recent-files-enabled          = false
  gtk-recent-files-limit            = 0
  gtk-recent-files-max-age          = 0
  gtk-theme-name                    = Adwaita

I can't reproduce that here.  My cursor is always filled so long as the
frame is focused.  The hollow cursor in my screenshot seems to be the
result of invoking scrot via gmrun, during which Emacs seems to lose
focus.  I don't know why that doesn't happen with Lucid; I assumed it
was just toolkit-specific behaviour.  [BTW, disabling blink-cursor-mode
does not change anything.]

Is this rather some kind of mishandling of focus events on Emacs' side?

Thanks,
