Update @ Martin
I further tested on several of my office systems and all experiencing the same thing, Its definitely a bug that need your squashing.
Didn't work. After adjusting my colors and size it started doing it again, same cores are hidden. Also I know this since I updated while sensors screen is open my screen blacks out/ flickers just for second and goes away, but once again, this wasn't present prior to any of the updates.
Something isn’t right with this release, rolling back to version 7 until this gets sorted out.
FYI. reason I'm pushing this is because I was considering few more licenses as I have # of workstations at mine and my wife's office, this just threw me off the excitement, so for now I’ll chill.
