Hello,
when I am in game, and press Shift+Tab, the Steam overlay does not want to open (literally nothing happens). I have the overlay and the shortcut configured in the steam settings.
Any ideas if this can be fixed, or is it just wayland problem that i have to wait out?
I don’t know how to fix your issue. But I can tell you that it works for me in Wayland (Sway). Maybe try and search for your issue paired with your specific desktop environment (KDE? Gnome?).
