Why doesn't plasma have an option for spanning wallpapers?
Why doesn't plasma have this feature? I'm pretty sure there is a technical reason. This is pretty much the most customizable DE in existence, and missing a small feature like this seems odd to me.
I want to take a shot at it, but I have zero idea where to start. Is there a guide on how to contribute to plasma? I've never done such thing. For now, I have forked superpaper and made it work with Wayland and I'm using it, but it would be nice to have that feature built in plasma
The linked ticket also references a merge request that went stale. So I would assume this is a good starting point (I haven't looked at the MR though, so I don't know how far off from the potentially accepted solution it is).
Most other DE's and even just regular WM's when used with feh can use a single large wallpaper spanning multiple screens, eg 5760x1080 for triple head. KDE 5 however can not do this and it also blocks feh from working as well. This used to work with KDE 3 and earlier but appears to have broken since then with the rewrite.
I wasn't sure which component was the better fit, Image Wallpaper or Multi-screen support so put it under Image Wallpaper since that is likely where it needs to be fixed.
