... > Thanks @sourcejedi! I've so far been unable to reproduce this on four different systems with Fedora 36 or Manjaro, Hi Robert. I got a new reproducer for Firefox, which doesn't use Xwayland. I ran this on my Fedora 36 system, the system that required a quick hand to reproduce with my .desktop file method. WARNING for people with photosensitive epilepsy. This will cause full- screen flickering. 1. Make sure user X is logged out, or at least not running Firefox. 2. Switch to a text console (ctrl + alt + f6) and log in. 3. `startx /usr/bin/fvwm` 4. Left click on the desktop to open the app menu. Open an xterm. 5. Open a second xterm. 6. In xterm 1, run `while true; do picom; sleep 0.1; killall picom; done`. The screen will now start flickering. 7. In xterm 2, run `firefox` Result: Firefox doesn't draw anything inside its window, or is completely black. -- 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: New 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.
