This fixes the issue for me: $ cat /etc/xdg/autostart/firefox-snap-launch-xwayland.desktop [Desktop Entry] Name=Launch Xwayland on startup of wayland session Comment=This allows to start the Firefox snap from the dock without a black window Type=Application Exec=sh -c 'if [ "$XDG_SESSION_TYPE" = "wayland" ]; then xrefresh; fi' TryExec=xrefresh OnlyShowIn=GNOME; NoDisplay=true
How about letting some package install that, or maybe make use of the xrefresh command in some other way. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1987976 Title: firefox black window Status in Mozilla Firefox: Confirmed Status in Mutter: New Status in firefox package in Ubuntu: Confirmed Status in mutter package in Ubuntu: Confirmed Bug description: nicolas@nicolas-fixe:~$ lsb_release -rd Description: Ubuntu 22.04.1 LTS Release: 22.04 nicolas@nicolas-fixe:~$ apt-cache policy firefox firefox: Installé : 1:1snap1-0ubuntu2 Candidat : 1:1snap1-0ubuntu2 Table de version : *** 1:1snap1-0ubuntu2 500 500 http://fr.archive.ubuntu.com/ubuntu jammy/main amd64 Packages 100 /var/lib/dpkg/status When I boot Ubuntu and start Firefox, the Firefox's window is totally black.
