... > 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 Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1987976 Title: firefox black window To manage notifications about this bug go to: https://bugs.launchpad.net/firefox/+bug/1987976/+subscriptions -- desktop-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
