Public bug reported:
Ubuntu 26.04.1 LTS
libadwaita-1-0 1.9.1-0ubuntu0.1
Expected: AdwSpinner / AdwSpinnerPaintable spinners (e.g. GNOME
Software "Loading Updates", GNOME Settings) should rotate regardless of
the selected gtk-theme.
What happened instead: With org.gnome.desktop.interface gtk-theme set
to any non-Yaru theme (e.g. 'Colloid-Grey-Dark'), every AdwSpinner is
drawn but never rotates. Hover/CSS animations work; the GSK renderer
(vulkan/ngl/cairo) makes no difference.
Cause: debian/patches/ubuntu/adw-spinner-paintable-design-and-animation.patch
adds update_animation_style(). When adw_settings_get_yaru_accent()
returns NULL (whenever gtk-theme does not start with "Yaru"), it does:
adw_timed_animation_set_duration (..., ADW_DURATION_INFINITE);
adw_timed_animation_set_value_to (..., 0);
This overwrites the upstream values (duration SPIN_DURATION_MS * N_CYCLES,
value-to N_CYCLES * G_PI * 2). With value-from = value-to = 0,
adw_animation_get_value() is always 0, so the upstream snapshot path
draws the same arc every frame.
Steps to reproduce:
1. gsettings set org.gnome.desktop.interface gtk-theme 'Adwaita'
2. gnome-software --quit, then open GNOME Software -> Updates -> Check for
Updates
3. The spinner does not rotate. Setting gtk-theme back to 'Yaru' makes it
rotate again.
