screenshot to show the 2 wallpaper selection pages, the broken and the working one

SUMMARY
Hi! I've been trying to change the wallpaper of my system under Mobian testing (plasma-settings 25.07) but the wallpaper KCM within plasma-settings doesn't work: it seems to select the image, but wallpaper is then not changed. On the other hand, the wallpaper selector that is accessed by long-pressing the homescreen works.

I've found [1] and agree with the long-term solution you wrote down. Of course, it will need someone with time and skill to implement that, as everything else.

In the meanwhile, would it be possible to drop the broken wallpaper selection page from plasma-settings? Thanks!
