Enabling "Enable background effects" does not properly work with dark themes

[pano9000]

Description

Hi,

was testing out the "Enable background effects" on a Win 11 computer today and noticed that it doesn't really play well with dark themes.

With Light themes it also kinda looks weird, but it is less noticeable -> kinda looks like it doesn't properly use the defined background colors, when the "Mica" option is active
