MacBook Pro 11,3 Nvidia Drivers

[blubee blubeeme]

I seem to be having issues recently when I build nvidia-driver from ports.

Installing 346.44 from pkg works fine but If I go and install 367.44 from
ports then my screen gets garbled and the nvidia driver doesn't seem to get
loaded, even though nvidia_load="YES" is still in /boot/loader.con but if I
revert back to 346.44 then things work again.

Is this a known issue? How can I fix/ avoid this?
