I cant speak for all B777, Im not sure if it is a real issue or if it is just a 'common' mistake made by the pilots.
SQ 777 that went off the runway at Munich a few years back touched down off center of the runway while conducting an autoland. The aircraft was aligned off centered because of another aircraft holding short of the runway, interfering with the autoland signals.
When the aircraft touched down off center, the captain was 100% sure that he hit the TOGA button (it could be heard in the cockpit voice recorder), but the throttle would not advance forward. Lucky for SQ, the aircraft came to a safe stop despite drifting into the grass, back on the runway and finally on the other side of the grass.
