I saw somebody reporting slow gnome-shell and it was, finally, caused by he changing some nvidia settings like forcing multisampling or anisotropic filtering in nvidia-settings, I guess would be interesting to suggest people to reset their custom nvidia settings if gnome-shell doesn't work ok for them. Reproducible: Always
This is documentation matter. Ebuild shouldn't have to deal with this imho.
