1874630 - [Wayland/hyprland] Dragging image causes Firefox to crash

Status: UNCONFIRMED

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

Description

[Adrian]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:121.0) Gecko/20100101 Firefox/121.0

Steps to reproduce:

Just dragged a image file (a PNG) from Dolphin on to about:newtab on Firefox (121.0.1) on a brand new profile. I use Arch Linux and I am on Hyprland.

Actual results:

Firefox sometimes crashes if dragging and dropping an image. (Might need to restart Firefox couple of times if it doesn't happen right away).

Expected results:

Firefox should not have crashed.

I've been able to find a way to reproduce the bug every time. Basically you keep dragging the image in and out of Firefox and it will eventually crash. It can also sometimes crash the first time you drag the image. I attached a video showing the bug.

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

The crash ID above is what happens when you do the crazy dragging back and forth (seen in the video). Here I have another Crash ID where I crashed when I just wanted to upload a image to discord (no crazy dragging): bp-d4c41376-de17-44c7-a3a4-53fb80240115

Please try latest nightly with wayland proxy:

Thanks.

I don't seem to be able to crash firefox anymore on nightly by just dragging the image once on discord but it's still possible to crash it by dragging the image back and forth quickly like in the video, only now it takes a bit longer to do it. Crash ID: bp-166caf49-01ac-4c49-93f2-2bb120240115

I forgot to mention, I used MOZ_ENABLE_WAYLAND=1 ./firefox -ProfileManager -no-remote command to launch Firefox Nightly.

It's "not a valid new object id (4278190116), message data_offer(n)" bug. Can you try to reproduce that in different compositor like mutter/kwin? (use nested session).
