Background of the Settings window is now all black (same as the text)

This happened for no apparent reason a few weeks ago. This hasn't happened to any other installed programs or store apps. And I didn't make any changes to Windows appearance or anything. In Windows Settings, "default app mode" is set to Light mode. (Default Windows mode is set to Dark mode, with "Windows color" set to purple - so my taskbar is purple).

I took a screenshot and opened it in an image editing program, and the text is exactly the same color as the background: #000000.

PS: The time display itself is fine, nothing happened to it. Just the Settings window.

Recently (few weeks ago) have upgraded to .NET 9 and enabled Fluent theme support #19. Indeed I did not really test it on windows 10, was under the impression that it will be a seamless transition, it is certainly due to this change.

If you set both App and Windows to the same theme, let it be Dark or Light, does the issue still persist?

Hi, thanks for your reply.

I tried all 4 combinations: setting the App and Windows to the same/different themes does not make any difference; but setting the default App theme to dark mode is a viable workaround, as it produces a readable D&T Settings window (black background, white text):

• Windows dark, App dark

• Windows light, App dark
  The Date & Time Settings window becomes legible (with black background and white text)

• Windows dark, App light

• Windows light, App light
  The Date & Time Settings window becomes illegible (black background and black text)
