Public bug reported:
I'm doing some code with Adw.Animation, but it doesn't work in Stonking
(although in Resolute it does).
This simple example shows the problem: it just jumps to the last
interpolation point. But the same code in Resolute goes through all the
intermediate values.
```
#include <gtk/gtk.h>
#include <adwaita.h>
static void
set_opacity (double opacity, gpointer user_data)
{
g_print("Valor: %f\n", opacity);
}
void activate (GApplication *app, gpointer user_data)
{
GtkWidget *window;
GtkWidget *label;
window = gtk_application_window_new (GTK_APPLICATION (app));
gtk_window_set_title (GTK_WINDOW (window), "Test Animation");
gtk_window_set_default_size (GTK_WINDOW (window), 400, 400);
label = gtk_label_new ("Hello, World!");
gtk_window_set_child (GTK_WINDOW (window), label);
gtk_window_present (GTK_WINDOW (window));
AdwAnimation *animation;
AdwAnimationTarget *target;
target = adw_callback_animation_target_new (set_opacity, label, NULL);
animation = adw_timed_animation_new (label, 1.0, 0.3, 900, target);
adw_animation_play (animation);
}
int main(int argc, char *argv[])
{
g_autoptr(GtkApplication) app = NULL;
app = gtk_application_new ("org.gnome.test-animation",
G_APPLICATION_DEFAULT_FLAGS);
g_signal_connect (app, "activate", G_CALLBACK (activate), NULL);
g_application_run (G_APPLICATION (app), argc, argv);
return 0;
}
```
And the makefile:
```
test: test.c
$(CC) -o test test.c `pkg-config --cflags --libs gtk4 libadwaita-1` -lm
```
In Resolute, it shows in the console the interpolated values. In
Stonking it just shows the last value, exactly as if the animations were
disabled in Accessibility.
Tested with libadwaita 1.10~alpha.1-0ubuntu3
