Okay, riddle me this one. I logged in to an xorg session, set the theme in qt5ct, and it displayed correctly (even though qt5ct complained that it wasn’t set up correctly); I then set the theme back to adwaita-dark (which is what I’ve been using while trying to figure this out. Logged out, logged back into a wayland session, ran qt5ct, set qogir, and for no apparent reason it works perfectly.
