Nautilus utterly unreliable with drag & drop

[Franck]

When using nautilus to drag & drop files between folders, it quickly becomes unresponsive and unreliable.

Giving a constant pattern to reproduce is hard, but playing a few tens of seconds with files and folders always triggers the weird behaviour.
This happens in a single nautilus window, or when using several (2) nautilus windows.
Sometimes, I get an error message saying my file does not exists anymore.

The problem is with D&D, as Using Ctrl+X / Ctrl+V always works.
Notice I'm using a Wayland session, it might be related...

Not sure how to collect useful informations to debug this, advices are welcome...

I've bben looking for similar issues on the net.
This one is unresolved but report https://bugzilla.redhat.com/show_bug.cgi?id=1229018
a comment describes what I see quite well regarding the error message:

"- when a drop fails in Nautilus and I use cut/paste to move a file or folder, I then get a "can't access [source folder]" dialog box a long time later (like 1 or 2 minutes, which is an eternity in UX terms) as if the mouse-based drag-and-drop got stuck all that time."
