Mica Backdrop effects not working properly on Windows 11 22H2

[Hassaan]

I was checking out the WPF UI and found that the Mica and Acrylic backdrop are not correctly picking up the light or dark palette set in the code. Instead, the effects are replying on the System/Windows Theme. 

If System Theme is set to Light, then the Dark Mode in RadWindow will not work correctly and similarly if System Theme is set to Dark then the Light Mode in RadWindow does not work correctly. This problem can be observed even in the Telerik's own control examples app.

Hi Hassaan,

Thanks for the provided screenshot - it was of great help!

We are aware of the described behavior. There is a public Bug Report on our Feedback Portal for it - Window: The control appears white when the Mica effect is applied to Windows 11 theme's Dark color variation. As you may see, the status of this bug report is completed and the fix for it is available with the 2022.3.1017 version of the LIB (from 17 Oct 2022). You can use this version, or wait for the UI for WPF's R3 2022 Service Pack which is scheduled for the middle of this week.

I hope you find the above information helpful.

Best Regards,
Vicky
