When login out of a current session or terminating the current session (shutdown reboot) I can see some strange graphical glitches, like the wallpaper is being pixelized.
I have a Dell laptop with hybrid graphics - NVDIA and Intel buildiin GPU.
I have tried both to install the newest NVIDIA drivers and remove all (including Nouveau) with the same results.
Now I finished in Wayland without any NVIDIA drivers at all and using Intel GPU, which is fine for me as I wasn’t using NVIDIA card recently anyways.
I’ve also tried to disable every GNOME extension I have with the same result. I’ve checked the error messages and cannot see anything relevant:
GLib-GIO-CRITICAL: g_bus_get_sync: assertion 'error == NULL || *error == NULL' failed
GLib-GObject: g_object_unref: assertion 'G_IS_OBJECT (object)' failed

upd1:
That looks like the issue appears only in Wayland or when Wayland is enabled.
Uncommeting the line
#WaylandEnable=false
in /etc/gdm/custom.conf
solves the issue but also forces it to use X11 which I’d like to avoid since Wayland has some advantages.
