Inaccessible background of the system keyboard in iOS 26 (liquid glass)

When preparing the app for the new iOS 26, I came across an unpleasant design decision. Specifically, in the new design, the keyboard has rounded corners, under which the system background is visible. And here we have only two options, a light/dark background, which breaks all keyboard calls in the application.

Can you tell me if there is any way around this problem?
