I think it happens when I switch away the monitors to another host on the KVM switch. Switching back later, I get only 1 display, problematic as some windows are on the non-working display. <alt><ctrl><f3> to console, both displays mirrored, with text mode login prompt. Then <alt><ctrl><f2> back to graphical display, gnome crashes, I get the gnome login screen. Things had improved a bit until amd's latest updates in 5.2.x.
