Do not force 1080*1920 for Spotlight

[RichardLuo0]

Describe your suggested feature

I like the wallpaper to scroll alongside icons, but for Spotlight, the wallpaper is forced to be 1080*1920, which makes it difficult to scroll horizontally.
However, the bing source allows me to select from different size, but no 1440p size, which I hope you can add.
