Quick update on this.
Still present with 3.4.1-0ubuntu1
However I followed a tip from the bug report linked in #10 (https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/964796/comments/4)
Switching OFF "Have file manager handle desktop" fixes the issue.
So seems to be related to this feature, "Have file manager handle desktop".
