Since I updated to Ubuntu 15.04 the application background and the background in the context menus is black in LibreOffice:
So far I have not succeeded in turning it back to the system colors.
- Manually changed the colors in Tools -> Options -> Appearance to white
- Turned off and on Tools -> Options -> Accessibility -> Automatically detect high contrast mode
- sudo apt-get remove --purge libreoffice* and re-install
None of those steps fixed the problem. Thanks for any help.
