Hi @bigbadbob2003

I've tested the changes you've made but I can't really figure out exactly how it's supposed to work. Regardless of running with --screen-root switches or not, I get a normal window that doesn't go to the background (I'm using i3 with picom). I guess you've tested it with some specific desktop environment? Could you add some extra information so I can actually test it?

I cannot merge it as is, but we can build upon this code and make it work when the situation is right if it's working on any of the desktop environments.

Hi @Almamu

Interesting there is obviously more involved to cover all DE's, i'm using budgie desktop environment with budgie desktop view.

I had no luck with the the screen-root switch which is why i have gone down the route i have, I looked into the way conky recommends putting widgets into the background and having them static across virtual desktops.

When i run it after the changes i made it goes fully into the background behind my desktop icons and static conky widgets, like this:

I'm guessing that i3 is doing something special with that window and that's why I see it as a normal one that I can move :/ (maybe the window needs some extra hints or something?)

The --screen-root switch is the mechanism the app should follow to select what screen you want to draw the background to, so before merging this pull request the code should at least take that into account.

There's of course some extra work required (like detecting when to use this method and when to use the old one, or a way to make this method work on everything else), but If this one works on more DEs that the one I already implemented that'd be a nice progress.
