Backdrop in virtual folder in detail mode

In detail mode, The "Name" field in my \Desktop and the "Oringinal place" in \Recycle Bin, there are no backdrop in displaying, I haven't coustomize a color in "Display → Fields" and I have enabled the "Enable background image in virtual folders" in "Display → Options"

Do you mean the sort column is using a color that you do not want?

For the Desktop folder, you can turn Preferences / Folders / Virtual Folders / Native display of the Desktop, including the following back on and Opus will handle the folder itself. When the option is off, Opus delegates the folder to Explorer, which will draw things differently.

For Recycle Bin, Opus always delegates the folder to Explorer. How Explorer draws its columns on top of the background is outside our control, and depends on the Windows version.
