I have Libreoffice 7.0 (Opensuse Tumbleweed). When I use the Breeze Light Theme, Writer shows the fonts preview without problems (in the drop-down menu, white background and black fonts). But when I use the Breeze Dark Theme, the drop-down menu fails: white fonts (in fact, light grey) with white background. When I disable de fonts preview in LO the drop-down menu looks normal (dark background with white fonts, obviously without preview). ¿How can I fix this problem? Thank you all.
Edited: Here’s a screenshot of how the problem looks:
