Hello. 
I’m using LibreOffice 25.2.2 on Ubuntu 25.04. I gave Dark mode (Tools > Options > LibreOffice > Appearance > Options > Appearance > Dark) a try but noticed that multi-line cells becomes black by default.
This was in a large spreadsheet, but I made a small example from scratch which seems to do the same. Is it that I have some color profile in LibreOffice Calc that I might have set previously or is it like this for everybody?

Best regards,
Have you restarted LibreOffice since setting Dark Mode? Not everything changes to dark mode until LibreOffice restarts
Thanks for the suggestion. I did try that, but still had the same result.
I tried renaming my ~/.config/libreoffice folder to reset whatever configurations I’ve made to LibreOffice… Then everything worked out of the box. Since my OS is set to “Dark Style” and Appearance is “System” by default in LibreOffice, it looked like I wanted with white text on dark background (irregardless of single or multiline).
Just to experiment further, I tried setting Appearance to Dark and restarted LibreOffice Calc. Then multiline text in cells became black and the other cells white. Then I tried to set it back to Default, but after restarting it I still had black multiline texts. So it seems once you start changing the Appearance value you can not get the default appearance anymore, which kind of seems like a bug to me.
I tested in Windows before and did not see the problem. I am now on a Mint Linux box and I can see the problem.
The solution is to go to Tools > Options > LibreOffice > Appearance, select Font color and change it to Automatic from Black. It looks like it had been changed in the Mint Linux installation before I upgraded to the LibreOffice ppa
