[Qemu-devel] [PULL 2/5] ui: fix icon display for GTK frontend under GNOME Shell with Wayland

[Gerd Hoffmann <kraxel@redhat.com>]

From: Daniel P. Berrangé <berrange@redhat.com>

The icon associated with a GtkWindow is just a hint to window managers
and not all of them will honour it. Some will instead want to show the
icon listed by the .desktop file. The desktop file is located based on
the application ID, which is set using g_set_prgname. QEMU has not
historically provided a desktop file or set its app ID, so it got a
broken icon in GNOME shell, which is now fixed.
