How is this related to gdm3?

This exotic configuration probably looks unsupported to
gnome-session-check-accelerated (the thingy that tries to guess whether
your system is 3D capable). Please file a bug upstream against
gnome-session, where they will ask for gory details.

This description is very confusing. Please provide a screenshot. The
“GNOME classic” mode doesn’t look like what you describe.
