It still returns false with 1.1.0 stable version... (Windows 10 21H1)

turns out this isn't a bug, the WinUI team have announced that acrylic will not be supported on windows 10. So much for down-level support

@Samuel12321: Can you give me the link to the announcement? It's quite disappointed :(

So, if acrylic is not going to be supported on Windows 10, then how did they made the acrylic effect on the new Windows Terminal application? 😕

The same on Windows 10 21H2 (19044.1889) with WinUI 3 - Windows App SDK 1.1.4.

windows terminal uses winui 2 islands

That is pretty backwards. Use the latest version, get less features and worse support.

Update: Desktop acrylic on Win10 will be supported starting in 1.2-preview2.
