The upcoming Debian 13 comes with GNOME48, but yaru-theme version is still 24.04. https://salsa.debian.org/desktop-themes-team/yaru-theme
This leads to a lot of incompatible besides gnome-shell<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1100949>, such as the icons cannot be completely covered because GNOME has made changes to the icons (like 'Wellbeing' in Settings), the window controls padding and margins is different with libadwaita. So, hope updates follow upstream 25.04 to adapting GNOME 48, so that will not have display problems when Debian 13 became Stable.
