Just for the records: This hint helped me!

I was figthing for HOURS with a nasty bug:
On an older Core2-PC with nvidia quadro PCI-E display card and Xubuntu
16.04 (fresh install) I have had the effect that my X11 display was
replaced with the one when I started X11, after switching the workspace.
I have to refresh the display with twice Alt-F11 to see the real display
again.

Disabling display composition fixed this problem!

Perhaps a bug in the nvidia xorg driver (NOUVEAU)?
