throwing nautilus to other screen ends up under launcher

[Humphrey van Polanen Petel]

I am using two screens with the right one being the default which has the launcher.
When I throw nautilus from left to right with <Ctrl,Alt,X>, it ends up with the top-left corner in the top-left corner of the screen underneath the launcher.
When I then throw nautilus to the top with <Ctrl,Alt,Up>, it positions correctly.
When I then throw nautilus back to the left screen and again to the right screen, it positions correctly.
Other programs (e.g. firefox) appear to behave correctly.
