1727006 - [wayland] Context menu appears in wrong place (or not at all) with 200% or 400% display scaling

Status: RESOLVED INCOMPLETE

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

Description

[Greg Hughes]

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:91.0) Gecko/20100101 Firefox/91.0

Steps to reproduce:

Enable 200% or 400% display scaling in GNOME display settings.
In Firefox, right-click links on news.ycombinator.com (note: all websites are affected)

Actual results:

Often, the context menu appears in the wrong place after a delay of a few seconds; or it does not appear at all; or it only appears for a fraction of a second. This occurs on Firefox 91 and nightly.

Expected results:

Context menu should always appear on right-click, at the location that was clicked, as it does with 100% or 300% scaling enabled.

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