I've attached a reproducer using SDL2, which was provided by a user in the bug reports upstream.
Unfortunately I couldn't reproduce the bug myself on 4 different machines with different hardware (including one virtual machine). The user on the bug report upstream also mentioned that they could only reproduce on one specific machine. This would be because the bug requires a very specific event sequence to trigger. -- 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/2093237 Title: gnome-shell crashed with SIGSEGV in meta_window_foreach_transient() from meta_window_has_modals() from repick_for_event() from meta_wayland_pointer_update() from meta_wayland_seat_update() Status in GNOME Shell: Fix Released Status in mutter package in Ubuntu: Fix Released Status in mutter source package in Noble: Fix Committed Bug description: [ Impact ] * gnome-shell may crash and log-out the user when closing a Wayland window that uses subsurfaces. * The crash is specific to certain applications and requires a specific event sequence to trigger, which makes it hard to reproduce. [ Test Plan ] 1. sudo apt install libsdl2-dev 2. wget https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2093237/+attachment/5853638/+files/sdl2-reproducer.c 3. gcc sdl2-reproducer.c $(pkg-config --cflags --libs sdl2) -o sdl2-reproducer 4. SDL_VIDEODRIVER=wayland ./sdl2-reproducer 5. Verify that a black window with a titlebar has opened 6. Close the window by clicking on the X button 7. Verify that the desktop did not crash and did not log you out. [ Where problems could occur ] * gnome-shell provides the GNOME desktop, and thus is a critical component. * A bug in the patch could manifest with applications not receiving mouse inputs correctly, or with the desktop crashing and logging the user out.
