Because I did not want to leak any personal data in the crash files, I reinstalled an Ubuntu 17.10 on another hard drive to have a fresh generic installation and did the tests there before rebooting on my regular installation.
There are two crash files, one for gnome-shell, the other one for XWayland. I put them in a zip file and, as it seemed big to me, I uploaded the file on my web server: http://mess.psydk.org/c18b_crash_firefox.zip Other observations: - I tested the problem with a X11 session, and I can reproduce it. - I tested the problem on Ubuntu 16.04 and I could not reproduce it. - I've been looking at Firefox source code, it calls gtk_window_fullscreen(). I wrote a program to repeatedly call that function but I cannot make it freeze. There is some specific X11 code in Firefox though that I did not integrate in my test program. Otherwise, are you able to reproduce the problem on your side? It seems quite easy to get. I will test other Ubuntu 17.10 installations tomorrow to get more statistics. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1749779 Title: System freeze when going back and forth fullscreen mode with Firefox Status in gnome-shell package in Ubuntu: Incomplete Bug description: Use Ubuntu 17.10 Open a Wayland session Start Firefox Press F11 repeatedly --> The System freezes ProblemType: Bug DistroRelease: Ubuntu 17.10 Package: gnome-shell 3.26.2-0ubuntu0.1 ProcVersionSignature: Ubuntu 4.13.0-32.35-generic 4.13.13 Uname: Linux 4.13.0-32-generic x86_64 ApportVersion: 2.20.7-0ubuntu3.7 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Thu Feb 15 20:09:27 2018 DisplayManager: gdm3 InstallationDate: Installed on 2017-10-02 (135 days ago) InstallationMedia: Ubuntu 17.10 "Artful Aardvark" - Alpha amd64 (20170926) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=fr_FR.UTF-8 SHELL=/bin/bash SourcePackage: gnome-shell UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1749779/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
