System Theme Overwrites LO Theme

Hello everyone,

I am using Linux Mint 22.3 and LibreOffice 26.2.

My problem is that my system theme (which is a dark theme, specifically “Mint-L-Dark-Red”) seems to overwrite the theme I choose in LibreOffice. If I set the LibreOffice theme to “Light”, the application nevertheless appears in a dark theme. If I change my system theme to a light theme, LibreOffice also appears in a light theme.

I can force LibreOffice to use a light theme if I run the application via:

GTK_THEME=Adwaita:light libreoffice26.2

However, I think this should be somehow solved in the UI of the application.

I was trying to find an open bug for this, but couldn’t find anything recent/open.

Happy to further discuss or provide more information.
