Sorry, previous message has wrong link.

Problem is caused by mutter merge-request 2241:
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2241 .
Shadow buffer is only used at software rendering.
Damage history is needed at copy from shadow buffer to onscreen,
to synchronize buffers.
I will open an issue upstream.

I also tried mutter 43.2-4 without the Debian patches,
specially the Support-Dynamic-triple-double-buffering.patch .
This did not solve the problem,
The only difference is that during blinking of the cursor
there is switching between 2 different (old) backgrounds i.s.o. 3.
Thank you for adding gallium i915 to mesa 22.3.2-1. Now at least the
default Debian testing release is usable at my laptop.
But the problem stills persists, if the i915-driver is removed and
kms_swrast is used.
In fact it is a mutter-problem (43.2-4) with shadow buffering.
Problem can be best
Hi Gert and others,
mesa Debian package 22.3.0-3 added again i915 gallium driver.
Can you try again with mesa 22.3.1-1, which is in testing now, and report back?
Thanks.
I installed all mesa-packages of previous installed version 22.2.0-1.
I also installed previous installed kernel 5.19.11-1.
With these versions the problem still existed.
Control: reassign -1 src:mesa 22.2.4-1
Control: severity -1 normal

issue, so I'm reassigning this. It also seems to be hardware-specific
and has a

This is expected. gnome-shell acts as the Wayland compositor (the X11
equivalent would be Xorg, window manager
If the i915 dri driver is present gnome-shell is using the DRM platform
(not the Wayland platform?) with this driver.
If i915 is not present gnome-shell uses the DRM platform with the
kms_swrast-driver!
I did not see this with the lsof-command, because the name of the
"zink"-driver was
shown
The Gallium dri driver i915 22.3.0 also at my laptop is working and
stops the flickering problem.
Unfortunately it still is not supported and also has issues.
Specially with shaders it is not compatible with classic i915.
Less shaders are compiled without errors and also there is no fallback
I was able to build a copy of the libgl1-mesa-dri with the Gallium i915
driver enabled, and that fixed the flickering problem on my netbook from
that era.
Here's a copy if anyone would like to try

I saw that Fedora had enabled it
I tried to install gnome-shell-common gnome-shell and
gnome-shell-extension-prefs 43.0.2.
This did not succeed because of failing login (protocol)?
Then I compiled source gnome-shell 43.0.2 and installed at /usr/local...
I verified the version with gnome-shell --version.

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

Are you sure that the root cause was this gnome-shell upgrade, and not
an upgrade of the mesa packages that may have happened at
Package: gnome-shell
Version: 43.1-2
Severity: serious
Justification: Policy 3.8
Dear Maintainer,
Recently a general upgrade was executed with gnome-shell
upgrading from version 43.0-2 to 43.1-2.
After this upgrade the gnome-shell wayland screen is flickering
and mangled at any action.
