Weird white macro blocks on encodes

[Kuno]

Using a 1080Ti to encode, 378.92 drivers, one of your custom builds of Hybrid (that had the subtitle issue back in March I want to say), and I am having these little white macro blocks show up in my encodes no matter what I am encoding.  Not sure if it's because my card is clocked so high or if it's just the nature of the beast, but I have not had them on my previous encodes with my 1080. https://imgur.com/eNecOYl https://imgur.com/TvEBCZw https://imgur.com/NZW8kPY

These white macro blocks aren't on the original source material, and they are very distracting to say the least haha.  I am using CRF 22 NVENC, 6 ref frames, main 10, with no filtering/deinterlacing or post processing.
