1631554 - [linux] Menu separators are almost invisible with native dark theme

Status: UNCONFIRMED

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

Description

[Ricardo Silva Veloso]

Attachment: Screenshot showing a context menu in system's dark theme

User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:75.0) Gecko/20100101 Firefox/75.0

Steps to reproduce:

1. Change the system theme to the dark variant (Adwaita Dark, for example)
2. Open a context menu, like the one in bookmarks tab

Actual results:

On Firefox 75.0 / GNOME 3.34, using system's dark theme (on Firefox's Default theme), context menus are dark, but separators are almost invisible. On Firefox's Dark theme, the separators on bookmarks bar becomes invisible too (doesn't affect the context menus).

Expected results:

Better contrast of separators.

I'm seeing a similar issue but also when using light theme (Windows 10 19042, resolution of 3840x2160 on Dell XPS 13 inches 9370): no visible separators on context menus

This bug is in Widget: GTK, and about dark GTK themes - please file a separate bug on the issue you're seeing, as it'll probably need a different fix. Please also check if the same thing happens in the default Firefox theme, and include your display and text scaling in your report (check Settings > search for "make text bigger", then note the values on the text slider and the "make everything bigger" dropdown).
