<pre>After setting GOBJECT_DEBUG=objects comparing the outputs
of the following program run with ITERATIONS set to 2 and 1:
#include <gtk/gtk.h>
#ifndef ITERATIONS
#define ITERATIONS 1
#endif
int
main (int argc,
char *argv[])
{
if (gtk_init_check (&argc, &argv))
{
int i;
for (i = 0; i < ITERATIONS; ++i)
{
GtkWidget *dialog;
dialog = gtk_file_chooser_dialog_new ("Open File",
NULL,
GTK_FILE_CHOOSER_ACTION_OPEN,
"Cancel", GTK_RESPONSE_CANCEL,
NULL);
gtk_widget_show_all (dialog);
gtk_widget_destroy (dialog);
}
}
return 0;
}
on Wayland the number of objects alive at exit increases for the
presence of few GdkFrameClockIdle objects.
The problem is that on Wayland popover GdkWindow have window_type
GDK_WINDOW_SUBSURFACE

and gdk_window_destroy (_gdk_window_destroy_hierarchy) does nearly nothing
for this kind of GdkWindow:

in particular it does not unref GdkFrameClockIdle objects it
creates.</pre>
