Hello Simon,
Unfortunately my 32-bit Dell-laptop does not crash and I think the
software-boys should not stop delivery of
software for older hardware, forcing to waste good working hardware.
Therefore I will use Debian testing as long as it supports 32-bit, so at
least some one is testing something at 32-bit.
My previous upgrade was 2022-11-06, the next failing upgrade was 2022-11-27.
It contains 921 packages; also upgrade libgl1-mesa-dri:i386 22.2.0-1
22.2.4-1 .
I am not sure problem is at gnome-shell itself.
I am almost sure it is not at mesa/swrast. I ran lsof for gnome-shell to
check the open files.
If the i915 driver is present at X and wayland the i915 shared library
is shown.
If the driver is not present at X the swrast library is shown, but not
at wayland.
Perhaps gtk/pango is used for software-rendering at wayland.
I will try to downgrade gnome-shell and dependent packages.
