#1101738 — Bug#1010357: gnome-shell: Gnome settings by gnome-control-center and other apps abort with SIGSEGV

Package: gnome-shell
Version: 42.0-4
Severity: important

Dear Maintainer,

As can be displayed by Firefox gnome-shell with wayland is using ES 2.0:
WebGL 1 Driver Renderer Intel Open Source Technology Center -- Mesa DRI
Intel(R) 945GM x86/MMX/SSE2
WebGL 1 Driver Version OpenGL ES 2.0 Mesa 21.3.8

With the current gnome-shell version 42.0-4 many/all graphical gnome apps
like gnome-clocks, baobab, gnome-character abort with segmentation failure.
Probably this is caused by using GL_HALF_FLOAT, which is not supported by ES
2.0.
The coredump shows address data is NULL.
A forced abort at _mesa_error shows it is caused by gtk-4.
At gsk/gl/gskglcommandqueue.c exist the lines:
glVertexAttribPointer (2, 4, GL_HALF_FLOAT, GL_FALSE,
and
glVertexAttribPointer (3, 4, GL_HALF_FLOAT, GL_FALSE,

gert@debian:~$ gnome-control-center
Mesa: User error: GL_INVALID_ENUM in glVertexAttribPointer(type =
GL_HALF_FLOAT)
Segmentation fault (core dumped)

Core was generated by `gnome-control-center'.
Program terminated with signal SIGSEGV, Segmentation fault.

I see you're using i386 instead of amd64. Do you still have this bug with amd64?

Thank you,

#1101788 — Bug#1010357: Extra info

I am using a DELL Latitude D620 laptop with Core Duo inside.
It only supports i386.
lscpu
Architecture:            i686
   CPU op-mode(s):        32-bit
   Address sizes:         32 bits physical, 32 bits virtual
   Byte Order:            Little Endian
CPU(s):                  2
   On-line CPU(s) list:   0,1
Vendor ID:               GenuineIntel
   BIOS Vendor ID:        Intel
   Model name:            Genuine Intel(R) CPU           T2400  @ 1.83GHz

I am running Debian Testing for a long time without this problem.
I have the impression somehow a switch is made to GTK-4.

#1101819 — Bug#1010357: extra info

No problem if I use:
LIBGL_ALWAYS_SOFTWARE=1  MESA_DEBUG=1 gnome-control-center

gnome-control-center also works if I use:
MESA_GLES_VERSION_OVERRIDE=1.0 MESA_DEBUG=1 gnome-control-center

(gnome-control-center:5552): GLib-WARNING **: 10:59:38.934: GError set 
over the top of a previous GError or uninitialized memory.
This indicates a bug in someone's code. You must ensure an error is NULL 
before it's set.
The overwriting error message was: Unable to create a GL context
Gsk-Message: 10:59:38.934: Failed to realize renderer of type 
'GskGLRenderer' for surface 'GdkWaylandToplevel': No EGL configuration 
available

gnome-control-center  works without error if I use:
GSK_RENDERER=cairo MESA_DEBUG=1 gnome-control-center

The program seems to work without problems, but I sometimes get errors:

(gnome-control-center:6102): GLib-GObject-CRITICAL **: 11:43:46.650: 
g_object_unref: assertion 'G_IS_OBJECT (object)' failed

(gnome-control-center:6102): GLib-GObject-CRITICAL **: 11:43:46.651: 
g_object_unref: assertion 'G_IS_OBJECT (object)' failed


Maybe you could reproduce the problem at a more powerful graphics card by:
MESA_GLES_VERSION_OVERRIDE=2.0 MESA_DEBUG=1 gnome-control-center
