    <thetext>Для falkon 24.08.3-alt1 в пакете нет зависимости от библиотеки libqt6-waylandeglclienthwintegration,
ни прямой, ни косвенной. Без наличия в системе libqt6-waylandeglclienthwintegration 
при запуске falkon не может создать главное окно и зависает на этапе его создания без отображения
чего-либо на экране.

Воспроизведение:
- запустить виртуальную машину с Live-CD на базе, например,
  https://nightly.altlinux.org/sisyphus/tested/regular-gnome-latest-x86_64.iso
  (https://nightly.altlinux.org/sisyphus/snapshots/20250115/regular-gnome-20250115-x86_64.iso)
- обновить до текущего состояния Sisyphus, 
  # apt-get update; apt-get dist-upgrade -y;apt-get autoremove -y;apt-get clean
- установить falkon,
  # apt-get install -y falkon
- проверить, что он запускается нормально.

- удалить libqt6-waylandeglclienthwintegration (есть в Live-CD по-умолчанию):

[root@localhost ~]# apt-get remove libqt6-waylandeglclienthwintegration

- запустить в терминале falkon:

Вывод
  qt.qpa.wayland: Failed to load client buffer integration: &quot;wayland-egl&quot;
не относится к wayland-egl, т.к.
[altlinux@localhost ~]$  rpm -aq |grep wayland|grep wayland-egl
libwayland-egl-18.1.0-alt1.1.x86_64


В обновляемых с более ранних состояний системах libqt6-waylandeglclienthwintegration может отсуствовать,
что приводит к неработоспособности falkon после обновления его до 24.08.3-alt1 .</thetext>
