Regression: Wallpaper page does not display wallpaper preview properly

[Spiritreader]

The wallpaper picker view does not seem to always display wallpapers, nor will it provide the wallpaper path when hovered over.

In the WallpaperPickerViewModel.cs, in the LoadSettings method on initialization, "SelectMonitor" is null, even though it should be populated, as a monitor is pre-selected in the list.

When changing the monitor selection after page load (from my MSI to the LG one) , it correctly steps into the OnSelectMonitorChanged function.

However this does not update the wallpaper preview.

@ChenYiLins could you please take a look?

Also, as an optional low hanging fruit, it would be cool if the set wallpaper path is always visible in a text section below the preview instead of only on hover with a card similar to this

Can reproduce with an update from version 10.x to 11, on Windows 10. I bet it's an issue with the saved data or a format, that causes bad or empty path?

After re-checking the code, it was really an oversight. Because the image display is bound to GlobalWallpaperSource, not GlobalWallpaperPath.
