I use GNOME 43.5 on ThinkPad T470S, I have 2 keyboard layouts, Russian and English. While Iam using Shift+Alt language changing but its strange. … → Russian → Russian → English ->… . The icon in right upper corner doesn’t change too, it changes only if I use Super + Space.
I have PC with the same GNOME 43.5, and there is no that problem.
