[Help Needed] Theme not applied for the lock screen. Also avatar is missing

[Pinkolik]

Expected behavior

1. When I hit Ctrl+Alt+L (lock screen) I expect to see Aether login theme.
2. When I log in for the first time after the boot, I expect to see my avatar in the circle.
3. I expect wallpapers constantly change.

Actual behavior

1. When I hit Ctrl+Alt+L (lock screen) I see the default theme.
2. No avatar in the circle.
3. Only one wallpaper image is shown for the whole time, I tried waiting, but it didn't change.

Steps To Reproduce
I use Xfce 4.18, and have following lightdm packages installed

lightdm 1:1.32.0-4
lightdm-gtk-greeter 1:2.0.8-3
lightdm-webkit-theme-aether 2.2.2-1
lightdm-webkit2-greeter 2.2.5-6

I have lightdm-webkit2-greeter configured as my greeter.

Screenshots

Additional context
sudo tail /var/log/lightdm/seat0-greeter.log is empty

Any fix for this one? I have the same problem with the avatar not showing.
