Windows 11 has received mixed reviews regarding its aesthetic appeal. However, for users who appreciate modern design elements, particularly the ‘blur’ effect, there’s promising news on the horizon. Until now, the application of the ‘Acrylic’ effect was restricted to the entirety of windows or contextual menus. Microsoft has announced intentions to expand this functionality, enabling developers to utilize the blur effect in specific areas of their applications, including pop-up notifications.
In addition, Microsoft has confirmed enhancements for WebApps2, making these applications feel more seamless and native to the Windows 11 environment. Notably, the tech giant is addressing an existing bug that has hindered the drag-and-drop experience.
Understanding Acrylic Material and Its Functionality
Acrylic material is a core component of Microsoft’s Fluent Design System, introducing a semi-transparent effect to selected regions within Windows 11. Users can observe this unique effect in action when accessing the context menu by right-clicking on the desktop, resulting in a “frosted glass” appearance.
Microsoft elaborates that Acrylic is intended for “transient, light-dismiss surfaces such as flyouts and context menus, ” as detailed in their support documentation.

Although Acrylic has been a feature for several years, its application was primarily limited to context menus until now.

Additionally, a different visual effect known as Mica is applied to the title bar, enhancing the integration of Windows 11’s theme and wallpaper.
Acrylic Blur to Expand to More UI Components
Currently, elements such as pop-ups, TeachingTips, ToolTips, Command Bars, Secondary Commands, and Combo Boxes do not offer the option for a semi-transparent effect. This limitation has been due to API restrictions, but that is about to change.
As stated by Godly T. Alias, a member of the Microsoft WinUI team, “This is the API Spec for the proposed SystemBackdropHost control for supporting the Acrylic effect in WinUI3 for controls other than Windows and Flyouts.”
Furthermore, Alias explained that developers can now easily incorporate a backdrop control wherever needed, ultimately increasing flexibility and enhancing visual design aspects.

This update empowers developers, potentially transforming the visual experience of pop-ups and other UI elements within Windows 11 applications.

Microsoft has even teased a demonstration app featuring the Acrylic backdrop applied to specific screen areas, showcasing a sleek and modern aesthetic. As developers begin adopting this innovative design, we can expect a more refined and visually appealing interface in Windows 11, complete with smoother animations.
It would not come as a surprise if essential Windows applications, such as File Explorer and Settings, also embrace this new approach towards incorporating a blurry backdrop for their pop-up elements.
