It is possible that the LED's are pulsed. While it may appear that that all are ON at the same time, they could actually operate in four phases. (each phase being approximately 25% ON time) Tying the gates together will create a single phase. Then there is the issue of "pull-up" or "pull-down" for the parallel gate drive scheme. Do you have enough or too much gate drive current?
