Created attachment 150652 [details] Wayland icons for firefox and thunderbird in task switcher I'm using a few GTK and Non-Qt applications like Firefox & Thunderbird (running with MOZ_ENABLE_WAYLAND=1), Sublime Editor, don't show their original icons in either task switcher or title bar, instead they show the Wayland icon. I've tried the same setting on Gnome Desktop, and it's not an issue over there, so I'm assuming this is fixable.

There is a bug in GTK(3) that causes most GTK apps to have wrong appids, which causes the icon to be missing See https://gitlab.gnome.org/GNOME/gedit/-/issues/486
