I'll add that I did do a weekly apt upgrade shortly before this happened, but
it's not obvious that any of the upgrades (firefox-esr grub-common grub-pc
grub-pc-bin grub2-common krb5-locales libgssapi-krb5-2 libgssapi-krb5-2:i386
libk5crypto3 libk5crypto3:i386 libkrb5-3 libkrb5-3:i386 libkrb5support0
libkrb5support0:i386 vim-common vim-tiny xxd) are relevant.
Thanks.

I'm going to guess that this is a change in one or both of:
- GPU firmware
- X11 GPU driver
Let's get the output from:
cat /etc/debian_version
to find out what you're running
lspci | grep VGA
to find out what your graphics hardware is
dpkg --get-selections | grep firmware
to find out what firmware is installed
dpkg --get-selections | grep xserver-xorg-video-*
to find out whether the right video driver is installed
and finally,
grep Driver /var/log/Xorg.0.log|grep II
or if that file is missing,
grep Driver ~/.local/share/xorg/Xorg.0.log | grep II
to find out what driver is actually being used
