This is an issue that's plagued me since first getting Traktor Scratch 2, and having just upgraded to Traktor Pro 4 I was hoping this would be magically fixed but unfortunately it's still there!
There's a bar that overlaps with the Artist name in the Decks UI, shown in the screenshot below (it should real as Alix Perez). Does anyone have any ideas on whether there's a workaround to avoid this?
