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
