Hello to you,
Thanks a lot. It seems it has something to do with Windows 11 acting differently from 10.

Windows in Dark Mode, frankly, for me, it is not really an option.
No offense meant, don't get me wrong.
I don't like 'dark modes' in any application.

However..., I did find quite a nice Start11 built in solution:
1. Enable "Enhanced taskbar settings" (gradient colour)
2. In 'Colour' select White

Looks fine.

Thanks again.

Quoting pelaird,

Try using these settings.

Yes Windows has two dark modes.  One for the taskbar / startmenu and another for apps.  Setting Windows mode to dark will give you a dark taskbar and thus white text.
