I have regedit open right now and Nvidia is at 2.23% with sudo perf top -p
$(pgrep Xorg). I'm even compiling the kernel and it's not slowed down at all,
and gotop doesn't show Xorg in the top 20 cpu processes. 

Obviously this is still an issue for some people (that is weird though, that
it's only some people that have the issue), but it would be nice if we could
figure out why some people say it's fixed, some people say it's not, and others
could never reproduce it in the first place.

I have 2 monitors and have for the entire time I've had an Nvidia GPU (over a
year), and haven't seen this issue once. 

That doesn't mean it's not in some way related to monitor setup, but it's not
"if you have an Nvidia GPU and multiple monitors you have this bug." 

I was hoping I could reproduce it so I could maybe try and test some stuff to
help debug it, but I can't do much if I've never had the issue and can't force
it.
