Another workaround mentioned on a dupe of the upstream bug:

I was able to further work around this issue by putting a script
into /etc/pm/sleep.d which simply "sleep"s for 3 seconds on
suspend and hibernate events. This lets gnome-screensaver and
xscreensaver to fade out fully before the system actually suspends
to disk or RAM.
