Windows 10 build 21376

Windows 10 build 21376.1 is the seventeenth Insider Preview build of Cobalt. This build was released on 6 May 2021 to all Windows Insiders on the Dev Channel.

Changes

 * A new font, Segoe UI Variable, has been added. It is a refreshed version of the classic Segoe intended to enhance legibility at small sizes and improve outlining on display sizes by including an optical axis so that font outlines can scale seamlessly from small to larger display sizes. It is incorporated with the OS and is being gradually adopted across visual surfaces by this point.
 * The icon for the Connect app has been updated to follow the Fluent Design language.
 * The Segoe UI Historic font has been updated to support Unicode characters from the Bamum range.
 * The drag-and drop default mouse cursor for scenarios such as performing the action into Office applications has been updated.
 * The sorting of symbols in the Symbols section of the emoji picker has been changed.
 * The new XAML menu shadows introduced in build 21354 are now more pronounced and now display along with the animation when using third-party display drivers.

News and interests

 * The flyout might occasionally flash in the screen's top left corner when opened.

Camera Settings

 * The Camera app does not respect the brightness adjustments made to a camera under its respective page.

General

 * The update process to this build has a chance of hanging for extended periods of time.
 * Certain parts of Search, including the File Explorer search box, are not displaying correctly in the dark theme.
 * Some devices may show a warning in the taskbar notification area stating that "your Windows 10 version has reached end of service".
