Hm, I know that there are some rendering issues when switching to or from dark mode. They also occur in the iOS version but are mostly limited to the navigation bars and the toolbar. This is a minor problem that was always present and I never managed to tackle. Some parts of the UI seem to be cached by the system and updating colors only takes effect after restarting the app or switching a couple of times between screens.
But something like in your screenshot where you can't read the song titles is new to me.
In any case, if the problem is no longer visible after restarting the app and only occurs when switching to or from dark mode, it is related to problems I know exis on iOS. But I'm not sure I can fix them.
