Are you using the Microsoft Store version of WDD?: No

Can you check if the same behavior happens when you manually switch between light and dark themes in Windows 11 Personalization settings? If so, this is a bug in Windows rather than WDD.

we checked this me and the other app developer, the problem is from your side(maybe the scripts or something)

For me, this issue occurs on the latest Windows 11 Beta build (22593.1) with WDD 5.1. I tick "Enable Night Mode," apps such as browsers switch to dark as expected but the system UI and the background remains light.

here is a demonstration:
your app does not refresh the system theme properly so the app looks like this:

after refresh(the supposed look of the app):

maybe the problem is with the scripts instead of the main app? idk i am not that geek with software engineering! i use it for beautiful looks on my windows pc

The same problem have bothered me for some time.
I just found that when you change the SystemUsesLightTheme in the registry directly to false, the taskbar stay the same while the start menu and icons operate properly. I wonder what changes have been made when you change the color theme in the system settings.

It seems like Microsoft has changed the behavior of the night mode shifting actions in recent preview versions.

The problem is still relevant in the latest version of windows 22621.1105

My system:

I checked the registry mentioned in the script. Things come strange.

Here's how it comes:

• If I change the color schedule manually in the Settings App, the registry value changes. Meanwhile the app windows and the taskbar changes color.
• If I click refresh wallpaper in WDD, the registry value changes to the same value as manually triggered. Meanwhile, the app windows changes its color, but the taskbar remains the same. After a restart it will sync the registry.

I guess that the Settings App has got some other ways to communicate with the taskbar, bypassing the registry.

Looking for a solution.

I have the same issue.
I think the font color and other system parameters must be called after changing the registry.
Furthermore, I think this is more related to WDD scripts than WDD itself. This issue is more about the System Theme switch/Application Theme switch.
Check my mouse script, How I called system parameters to update the new mouse value.

$CSharpSig = @’
[DllImport("user32.dll", EntryPoint = "SystemParametersInfo")]
public static extern bool SystemParametersInfo(
             uint uiAction,
             uint uiParam,
             uint pvParam,
             uint fWinIni);
‘@
$CursorRefresh = Add-Type -MemberDefinition $CSharpSig -Name WinAPICall -Namespace SystemParamInfo –PassThru
$CursorRefresh::SystemParametersInfo(0x0057,0,$null,0)

Mouse script where I called system parameters to update their mouse values:

You just need to know which API needs to be called to update these values. Maybe use Process Monitor v3.92?
