How come on other people's setups (in GNOME and Budgie - I use GNOME) applications have their icon displayed in the top-left corner (eg the Lutris icon in Lutris or Nautilus icon in Nautilus)?
You can see the icons eg in joshontech Monsieur_Caillou and JohannPopper posts.
These icons don't display for me, does anyone know what to do to make them display?
Edit:
OK, I know how to enable them - for them to appear, you need to disable application menu in top bar settings in GNOME tweaks.
The application menu option didn't work for me anyway (nothing appeared on the top bar), so there was no downside to doing this.
