iOS 7 is doing some things under the hood that are not documented. However, you can examine the view hierarchy and adjust the relevant views by overriding -willMoveToSuperview in your custom input view. For instance, this code will make the backdrop transparent:

- (void)willMoveToSuperview:(UIView *)newSuperview {

    NSLog(@"will move to superview of class: %@ with sibling views: %@", [newSuperview class], newSuperview.subviews);

    if ([newSuperview isKindOfClass:NSClassFromString(@"UIPeripheralHostView")]) {

        UIView* aSiblingView;
        for (aSiblingView in newSuperview.subviews) {
            if ([aSiblingView isKindOfClass:NSClassFromString(@"UIKBInputBackdropView")]) {
                aSiblingView.alpha = 0.0;
            }
        }
    }
}
