There's probably no way GDM could cause this directly. But indirectly if you are logging into a Wayland session in one case and Xorg in the other, then that might be the main factor here.

Please try logging into both Xorg and Wayland sessions to see if one works better.

Also, for Nvidia there used to be settings to control tearing in the nvidia control panel. So you shouldn't need to "To get rid of tearing I added nvidia-drm.modeset=1"...?
