mate-screensaver crashes, leaves screen unusable

When the screensaver starts, the screen is covered with a black screen at
about 15% transparency. At maximum brightness, it is just possible to see
the pointer and exit programs and type into windows, but the overlay stays
and I have had no luck eliminating it. Even exiting X and dropping into a
text vty leaves the overlay in place. I had to reboot.

This started after updating to drm-61-kmod which allowed the Alder Lake
graphics to load its microcode and enable  capabilities beyond the most
basic. Before that, the screensaver simply did not work. I'd love to get
the screensaver working again!
