I am getting strange coloured pixels over my picture when processing in LR cc

Someone brought this issue up in Oct 2017 but there was no resolution, so I am wondering if three years later there are any new thoughts on why it is happening and what to do about it? I am using LR CC, it is up to date with updates. I have a new laptop with 16 gb of Ram and 1 T harddrive which is mostly unused. My computer meets all the requirements of LR and Photoshop in specs. I have a NVidia 2060 RTX 6 gb Ram video card and it is on under preferences. I have setup plenty of cache memory in preferences. I convert from RAW to DNG and then process the DNG. It happens randomly and does not seem to be particular to one picture file. If I shut down the program and come back in the picture is no longer strangely pixelated, but another might be. It is not every day but it happens often enough that I am wondering what is happening. It usually happens in develop but this time it happened in library as I was in survey view.

This is today's version:
