Gnome shell/mutter crashes on wayland
Last modified: 2016-11-10 13:03:53 UTC
Created attachment 318289 [details] Information about core dump About two or three times a day gnome shell crashes. From the GUI point of view I applications are no longer accepts input from mouse (clicking, scrolling), but the shell itself still works, I can switch between windows by clicking on them, but no interaction possible within window of applications. Surprisingly keyboard keeps working, I can type and navigate. When I log out and log in back, mouse starts working again. Environment: OS: Arch Linux Kernel: 4.3.3 Gnome shell: 3.18.3 Mutter: 3.18.2 I didn't notice any specific action which triggers the error, however the log below and the attached core dump may tell more about the problem.

Created attachment 318292 [details] Backtrace with debug symbols
The reason of crash from the core dump looks like https://bugzilla.gnome.org/show_bug.cgi?id=751847 - the meta_window_unmanage() sets window->surface to NULL and then meta_wayland_surface_configure_notify() dereferences the surface. This crash occurred on exit, but you said there are crashes when running. They may be due to the same reason. This bug can be hit even after closing a window when some grab is active https://bugzilla.redhat.com/show_bug.cgi?id=1293479. That would explain why you're mouse is not working properly. But this is not 100%.
This bug should be gone in 3.22 according to https://bugzilla.redhat.com/show_bug.cgi?id=1214462 (via comment #2). Can you confirm this?
I can confirm that the error related to meta_wayland_surface_configure_notify() has gone away. Unfortunately today I run into another bug which has the same symptoms like the previous one. Gnome Shell is responding, applications accept keyboard events, but ignores mouse (clicking, scrolling does not work). It's not clear from the logs what crashed exactly in the Wayland/X11 composition. See the attached gnome_on_wayland_3.22.1_dmesg.log file for details.

That looks like a different bug: https://bugzilla.redhat.com/show_bug.cgi?id=1358700 (there is also a similar bug where applications don't react to keyboard events: https://bugzilla.redhat.com/show_bug.cgi?id=1358889)

I have the exact same problem as it's described here: https://bugzilla.redhat.com/show_bug.cgi?id=1358700 So this one seems to be resolved.
