The title pretty much sums up the problem. Each time I log out or reboot,my lightdm wallpaper shown at the login screen stays the same, even when the random button is the default selection. If I repeatedly click the random button it will randomly choose another wallpaper but this will remain the same on logout or reboot whereas before, when the random button was selected, I would always get a different wallpaper when I booted up or logged out to lightdm.

I’ve noticed this happening for the last couple of weeks. I’m on the latest version of lightdm-webkit-theme. Can anyone else confirm this behaviour? I have witnessed it on both my laptop and desktop PC. I know it’s hardly the bug of the century but thought I’d make the devs aware nonethless.
