hp prime flickering when scrolling

[KaLi]

Hello to the long-time Prime users,

as a new Prime G2 user I would like to ask a (maybe redundant) question. I would like to understand if my device works to it's standard specifications and nothing is faulty.

In Home/CAS-Screen, when scrolling the screen is "flickering" very heavily -- looks bad, but isn't... that was the topic of the thread-starter.

But when I'm in Home/CAS and do nothing... not touching anything... only watching the screen... meditating the typed in maths... sometimes (in range of some seconds) single horizontal lines flicker here and there randomly over the screen.

My Question, therefore: That is also the normal behavior?

The flickering doesn't bother me at all -- it's barely noticeable... but I would like to exclude the possibility that my LCD driver is faulty and will die (just outside of my return-warranty ;-) .

Thanks for an answer in advance. I would guess such questions bother many new users of this otherwise remarkable device.
