The hearham.live RepeaterSTART application no longer has an app icon in the Alt+tab switcher on Ubuntu... or the app switcher on Librem phone. Now I recall this had been working and I am wondering why this piece of code doesn't seem to work anymore?

if os.path.exists(icon_app_path):
pixbuf = GdkPixbuf.Pixbuf.new_from_file(icon_app_path)
self.set_icon(pixbuf)
