GPU memory is overloaded I'm using iStats Menu to monitor the loading of my MBP.
And when my external 4k monitor LG 27UK850-W is connected via USB type C I can see that my GPU Memory is overloaded (currently 744%), though Processor seems fine.

Is it a bug or it should be this way?

And of course, Fans are almost always on. Is it ok?
It appeared to be an "iStats Menu" issue
And it is fixed in the newest version
