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
