Description Mateusz Mojsiejuk 2019-02-13 14:13:35 UTC
Description of problem:

Version-Release number of selected component (if applicable):

Fedora 29 ,  


How reproducible:

Steps to Reproduce:
1. Start firefox-wayland, have multiple tabs open in ff.
2. Pull one tab out and move it to secondary monitor and back a couple of times
3. Behold results

Actual results:
Gnome-shell hangs completely and stops updating screen (sound is still coming through so believe all processes keep running)

Expected results:
Window should move between the two monitors in a multi-monitor setup

Additional info:
hard - resetting and booting again and the computer works
but if you start firefox-wayland again and it has restore previous sessions
enabled you will trigger the same bug causing an instant crash of gnome-shell again.

One has to start ff with another profile , or start the non wayland version of firefox to undo the tab on the secondary screen.

After having installed the debug symbols of the mutter and gnome-shell packages, can you run the following:

sleep 10 && pstack $(pgrep -u $USER -x gnome-shell) >& gnome-shell-backtrace.txt

then within 10 seconds, reproduce the freeze you are experiencing? It should hopefully log where gnome-shell got stuck. Attach the resulting file here. A piece of the journal from when gnome-shell got stuck would help as well.

The attached files above were generated on firefox-wayland-65.0.1-1.fc29.x86_64

Comment 5 Jonas Ådahl 2019-02-28 13:25:55 UTC
Any chance to get get a backtrace with debug symbols (for mutter, gnome-shell and glib)?

Comment 6 Mateusz Mojsiejuk 2019-03-22 10:55:26 UTC
I can no longer reproduce the issue, So I think it can be set to solved.

possibly in the firefox release yesterday as I noticed I'm on:
firefox-wayland-66.0-6.fc29.x86_64 now
