Bug#1025213: gnome-shell: Flickering and mangled screens on wayland if dri driver not available

[Gert van de Kraats]

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.
