Ubuntu dark theme on Zotero 6 all messed up

neti

Hi,
a few small issues I'm having with dark theme on Ubuntu 20.04 / Zotero 6.0
- the top row with the columns name is light-gray-on-white

When I open a PDF in a tab
- the unselected tabs titles are black-on-dark-gray
- when I get back to the main page the whole top row (which was dark before) now is light-gray
- the the item names and the note titles on the right note column are both light-gray on white.
- in the searchbar within the notes the text is black-on-dark

Thanks
