Hello,
In Tools/Options/LibreOffice/Appearance/LibreOffice Themes: I added a theme with an earlier version of LibreOffice and I can"t remove it.
I"m using version 25.8.2.2.
I would like to remove it because there is a bug somewhere. Indeed, the color of the window of this theme systematically changes to black with each update of LibreOffice and I don"t understand why.
