How to eliminate flickering windows interface?

Question

Windows

Win 8.1 is installed on the laptop, around the beginning of April there was a problem with interface flickering in some programs. Video with an example
I'm working with an external monitor connected via HDMI, therefore, a discrete video core is responsible for displaying the picture, I have it Nvidia. At first, I sinned on video drivers - because of this, I installed both older ones and those that are offered in the system update center and the latest ones. I even reinstalled the system.
I tried to work without an external monitor so that the picture is displayed by the intel core (there are also the latest drivers here) - the same problem.
I still don’t understand what this flickering is tied to, it doesn’t depend on the load, it doesn’t depend on any special actions either, sometimes it’s enough just to move the cursor to some element or simply expand the window with the program. The only way I managed to reproduce it myself to record this on video is that any change in appearance in the system settings entails this flicker.
Help, please, deal with this problem, tk. during this flicker, the system does not respond.

Answer 1

Well, generally speaking, a discrete video in a hybrid video does not have a video output and the image is always output through an integrated video card, even if it is rendered by a discrete video. But that is beside the point. I observed something similar on the same computer with the eight, and this led to software crashes somewhere in the depths of MSVCR120.dll and I have not yet found a solution.
