In Cubase 15 and later, folder-color inheritance works as intended, but a minor graphical bug appears when interacting with folder tracks. Functionality is unaffected, though child-track headers can briefly show an unintended overlay. A screenshot with reproduction steps is attached.
This did not occur in Cubase 14, and some users may prefer having the option to use the previous folder-track behavior.
Bonus: Automation lanes currently appear noticeably darker within the folder-color hierarchy. A proposed adjustment is attached for a more consistent and visually balanced result.
In #3, the overlay slightly overlaps the header by a pixel or two. It’s minor, but still part of the issue, and I think resolving it will require a more dynamic approach that checks multiple scenarios.
