1899494 - Firefox crashes in Gnome when tiled in a screen bordering another screen

Status: RESOLVED FIXED

(Core :: Widget: Gtk, defect, P3)

Description

[Daniel Vianna]

Attachment: Display layout

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36

Steps to reproduce:

Please refer to my display layout: https://imgur.com/a/RIQGeUF

1. Log into Gnome 46 (Fedora 40, Wayland)
2. Start Firefox
3. Use super + arrow to tile Firefox to the right side of display 1
4. Press super to turn to activities overview (Firefox crashes)

Same happens if you substitute step 3 with

• tile Firefox to the left side of display 2;
• tile Firefox to the left side of display 3.

Firefox as a free-floating window, maximised, or tiled to a side not bordering another display does not crash.

Actual results:

Firefox crashes

Expected results:

Firefox does not crash

It may be dupe of Bug 1885831.

Please try this build. You need to download the tarball, extract it and run on terminal as ./firefox -P and create a new profile and test it:
https://firefox-ci-tc.services.mozilla.com/api/queue/v1/task/As8eV0xAR4y-C2V-6o5Bew/runs/0/artifacts/public/build/target.tar.bz2

There's more info how to run Firefox with different profile:

If you can reproduce the crash, please attach log from:

WAYLAND_DEBUG=1 MOZ_LOG="Widget:5 WidgetWayland:5" firefox > log.txt 2>&1

Thanks.

No, the nightly build does not crash on my machine with a new profile. It runs fine.

Is the nightly build good for personal use? Or is there a release that should be working too that I can be using for the time being?

Once confirmed / fixed will backport the fix to beta/release. Stay tuned.

Can you please test this build? It's more fine-grained fix:
