It's broken also in qt5.

I found the reason why lxqt-config didn't set wallpapers here:

I use a symlink ~/.local/share/lxqt/themes → ~/git/lxqt/lxqt-themes/themes for testing modified themes and PRs.

Using the non local themes it works as expected, but it's still an issue for local themes where "use wallpaper from theme" will never work.

I wasn't able to reproduce this. I put a theme inside ~/.local/share/lxqt/themes/ and the wallpapers folder inside ~/.local/share/lxqt/, and the wallpaper was changed when I selected and applied that (user) theme.

I also tested with a personal theme, whose wallpaper was inside its folder. Again, the wallpaper was changed correctly.

Actually I never looked at the wallpaper.cfg ... it's a relative path ../../wallpapers/ and I've no wallpapers there.
