Every time I reboot, some of my desktop icons disappear from screen 1 and appear on screen 2.
If I try to move them back, KDE shows the normal copy/paste context menu. But if I set screen 2 to folder view then back to desktop mode, all icons move back to screen 1 automatically.
I think there must be some config file for each screen, set to folder view mode, but I can't find where it is.
(I'm using Kubuntu 18.04 with KDE Plasma 5.12.5)
