I've added some menus to the new (mac-like) menu bar on the iPad App under iPadOS 26, which is working fine.
However if the main view controller covers the whole screen and shows a fullscreen Map (MKMapView), the menu bar has a dark gradient as a background, which makes it extremely difficult to see the menu.
I guess the iPadOS tries to put a semi-transparent layer between the view controller and the menu bar to make sure that the content of the view controller doesn't interfere with with the menubar and the menu is easy to read. But when the view controller shows a map, the system seems to get the colors for this transparent layer wrong.
Is it possible to solve this, or is this still a bug of iPad OS 26?
Interestingly, when I create a screenshot of the screen, this dark gradient which makes the menu bar unreadably is not included in the screenshot. So in the screenshot the menu is easy to read. Only on the real device, the menu bar is almost unreadably
