This could be one of two issues:

• You're using Wayland instead of X (wallset is programmed to work with X) OR
• Whatever GNOME is using to set the wallpaper is over the X wallpaper.

If you are using Wayland instead of X, you can switch to X by logging out, pressing the gear at the bottom right and pressing something like "GNOME on Xorg" then logging in.

Reproduced on X11 running pop!_OS 21.04. It's not related to Wayland.

Could this be related to an OpenGL configuration of the nvidia proprietary drivers?

When i logout and then login
I'm able to see the video wallpaper set using wallset for a brief moment
I think its related to nvidia drivers

Tested on gnome 43.3
