Fake transpacency background

[dougneves]

Hi, picom community!

Is it possible to select an image on picom as the background image, different from the image set in the wm background?

What I'm trying to do: have an image as my background, and an edited version of this image as the background on picom. This second image will have some blur effects and different colours. I don't want to use the native blur and shaders from picom because I want to preserve the system resources.

Currently, I use i3wm, with nitrogen to set the background image, and I have transparent-clipping set to true on the picom config.
