(This probably belonged on debian-user, but since I have background on
this specific problem and already did the research.)

Ctrl-Alt-F7 will also restore the desktop (which I think is just another
version of your solution 2 of switching VTs).
This appears to be a bug in light-locker specifically, which is the
default screen lock program with XFCE with lightdm. See, for instance:
Switching to another greeter from the default gtk-greeter appears to help
according to that bug, which may mean that the bug is actually in
lightdm-gtk-greeter. There doesn't appear to be a Debian bug for this; it
might be a good idea to open one against light-locker (or, if you confirm
switching to slick-greeter per that bug, lightdm-gtk-greeter).
