1528021 - Firefox uses deprecated gtk-menu-popup causing issues in Wayland

Status: RESOLVED DUPLICATE of bug 1423598

(Core :: Widget: Gtk, defect)

Description

[Jonny Mako]

Attachment: ffmenu.png

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:67.0) Gecko/20100101 Firefox/67.0

Steps to reproduce:

1. In a wayland compositor (weston for example) open Firefox nightly with GDK_BACKEND=wayland
2. Right click on the right edge of the firefox window

Actual results:

The context menu is rendered partly outside the firefox window.

Expected results:

The context menu should've been re-positioned to appear fully within the firefox window.

This is caused by firefox using the deprecated gtk-menu-popup. This should be updated for Wayland backends. In addition to popups being rendered off-screen, they are also mispositioned away from the point of the right-click. Here are a couple of relevant links:

This affects the behavior of firefox wayland on Sway WM for example:

This looks like a duplicate of https://bugzilla.mozilla.org/show_bug.cgi?id=1339920 and/or https://bugzilla.mozilla.org/show_bug.cgi?id=1423598.

The issue is also present on other wayland compositors such as GNOME.
