'get' command returns the same wallpaper for different screens with different wallpapers.

This is on Mojave. It reports the same wallpaper across both screens, but only the first screen has the reported wallpaper.

In my case, it is behaving as expected in macOS Mojave.

Odd...
What's your OS version and build number, wallpaper version number, and the setup of your screens?

macOS 10.14.3 (18D109)
wallpaper v2.0.0 (installed using brew cask)

one external display, with the built-in display as the main display.

All the wallpapers are specified individually.

after some tests, I suspect this to be a macOS bug instead of something related with wallpaper.

Here is what I have tried:

1. remove the database file located at ~/Library/Application Support/Dock/desktoppicture.db
2. try to set desktop pictures for both the built-in and external displays, to keep things simple, both are set to a single image.
3. use sqlite3 to check the freshly created desktoppicture.db

it seems that after desktoppicture.db is recreated, the first desktop picture change would not be logged in this file.

wallpaper v2.0.0 (installed using brew cask)

macOS 10.14.4 (18E226)
Also wallpaper v2.0.0 through brew cask.

one external display, with the built-in display as the main display.

I have one external, but it's my main, and my built-in is the secondary.

All the wallpapers are specified individually.

I have a massive folder of nice high-res wallpapers that I pointed to; they rotate every 30 minutes.

it seems that after desktoppicture.db is recreated, the first desktop picture change would not be logged in this file.

Interesting findings. I checked the database myself - both of my pictures are in there. I will try re-creating it and see if it stops appending them to the data table. I'm not super clear yet on how macos-wallpaper scours the database to figure out which wallpapers are in use for each desktop. I don't know Swift but looking through the code it looked like it uses macOS API calls to figure it out, rather than anything to do with this database.

Correction of my setup:
macOS 10.14.4 (18E226)
wallpaper v2.0.0 (installed using brew cask)

one external display used as the main display.
