iOS 26: Enabling "Reduce Transparency" causes a persistent white bar where the tab bar was hidden, blocking user interaction

Hi everyone,

We're experiencing a bug on iOS 26 that only occurs when the user has Reduce Transparency enabled in Accessibility settings.

App structure:

Our app uses a TabView with a standard tab bar. Inside each tab, we use a NavigationStack. The tab bar is visible on root-level screens, and hidden on all pushed destinations using:

.toolbar(.hidden, for: .tabBar)

The problem:

On iOS 26 with Reduce Transparency off (Liquid Glass active) — everything works correctly. The tab bar hides as expected.

On iOS 26 with Reduce Transparency on — a white bar appears at the bottom of the screen in every place where the tab bar is hidden.

This white bar:

Overlaps content at the bottom of the screen. Blocks scroll, tap, and all user interactions in that area.

We also tried:

.toolbarBackground(.hidden, for: .tabBar)
Removing all custom UITabBarAppearance configuration

The only workaround we found is setting UIDesignRequiresCompatibility = YES in Info.plist, which reverts the entire app to the pre-iOS 26 design — not a viable long-term solution.

What can we do? Thanks in advance.
