Can you confirm that clipboard content always appears in the clipboard history? I assume you use Ubuntu 17.10?
On my VirtualBox Ubuntu 17.10 test environment occasionally when copying from a Wayland application (mainly Gnome Terminal) content doesn't show up in history (as clipboard change is not triggered by Wayland it seems). I tested on another physical machine on one of my colleagues with Wayland and there clipboard always worked with this fix. It was on a different distribution though.
Results are a bit mixed and I am wondering whether the problem simple appears with VirtualBox.
Thanks Olivier for your feedback.
