Well, there is indeed a small delay in the rendering, but not the workspace switching itself, because I spawn a process in the background using imagemagick and feh doing the heavy lifting. It is not the most beautiful thing but it works quite well! 2015-02-28 18:09 GMT+01:00 Brandon Allbery :

I have written a log hook to set wallpapers. The special thing here is, that you can assign a wallpaper (or a set to be chosen randomly from) to each workspace, so when you have workspace A on screen 1 and B on screen 2, you see the according images on these screens and if you swap the workspaces, the wallpapers get swapped too. Wallpapers are always applied scaled and it detects vertical screens and rotates images accordingly (so any wallpaper will be rendered on any screen in a sane way).

The main reason this hasn't been done already is that it tends to "lag" workspace switching. On a fast enough machine, it can work; on slower ones, the trick used by most desktop environments is preferred (a window per workspace that sits under all other windows). Not saying this is a bad idea, just mentioning.

That is the most ugly part about it - I take the pictures, get the screen rectangles, transform the pictures accordingly and stitch them together to a huge picure of the virtual xinerama screen size. Then it is rendered onto the root window and each monitor (as a view onto the virtual huge screen size) shows the wallpaper I put into its rectangle. 2015-02-28 18:14 GMT+01:00 Brandon Allbery :

One thing that occurs to me is what happens when you switch between multiple workspaces very quickly. Also, how does this work in multihead setups?
