I have also noticed this annoyance on several machines and different
linux distributions so it must be an Xfce problem, not a Qubes problem.
You're probably asking yourself why do we even need xscreensaver when we
can instead use a screen locker like lightlocker. I think I read on the
issues tracker that xscreensaver is the most secure screen "locker" for
X11 which is why it is used in Qubes, and if you would want to use
something stronger you'd have to go wayland.
I hear Qubes 4.1 will use the new Xfce 4.14 though I am unsure whether
this bug has been fixed in that version.
Kind regards!
