--- Comment #7 from stragu <stephane.guillou at member.fsf.org> ---
Thank you for clarifying, Stuart!

Confirmed by using the dark mode in GNOME 3.36. Even though the GNOME dark mode
uses a dark grey as a base, it is evident that the button text in question has
either a poor contrast (in the case of GNOME dark mode) or disappears entirely
(for dark modes that use black as a background, as in this bug report's
description).

The buttons in question are the right-hand side menus in the tabbed user
interface, in all ribbons. The File ribbon happens to have two (File and Help),
as well as an extra menu button exhibiting the same issue: Recent Documents.
All other ribbons only have this issue with the right-hand side button of the
same name as the ribbon.

To reproduce:

1. Set the OS's appearance to a dark mode
2. In LibreOffice, set the user interface to Tabbed: View > User Interface... >
Tabbed

Note that this issue also exist for some dropdowns in at least two other user
interfaces: Tabbed Compact and Groupedbar compact.

Changing Blocks to more specific meta bug, and changing the title to more
accurately describe the issue.
