This problem is mentioned in many different threads for a month or so. Everyone seems to say that if you have the older 4080 version graphics driver from the NUC driver bundle it does not have that problem. The following link tells how to download a Beta driver which greatly improved the flickering-after-resume problem for me, but I have reported that I sometimes have a problem where there is still an inch of so of flicking down at the bottom edge of my screen. Beta Intel® Iris™ and HD Graphics Driver for Windows* 7/8/8.1 32 & 64-bit versions 220.127.116.1106 for Haswell and Broadwell
Many thanks. I'll try this.
