After installing 384.47 on a system with two 4K monitors connected by DisplayPort, I get an occasional flash/flicker on each monitor. The interval is random and sporadic, sometimes with 30sec between flashes and sometimes multiple minutes. Both monitors are affected, though they do not flash at the same time. It seems that the flashing is likely related to PowerMizer, as the flash always occurs after a decrease in the PowerMizer performance level. (Not every performance level decrease results in a flash though.)
I have attached the output of nvidia-bug-report.sh.
