Screen glitches and becomes unusable after some time of usage

[oleg_milan]

Laptop screen is almost unusable.

How to reproduce:

- turn off Laptop for ~1 day

- turn on Laptop and run some apps, like Chrome

- after 10-30 minutes of usage(usually) screen start to glitch, flicker and become unusable and it's getting worse and worse until screen is not usable and not responsive at all.

It seems, like the issue is starting to appear after switching between apps, especially, when apps has a completely different colors, like from white to black and not due to a mechanical reason(open/close display)

And more interesting facts:

1. After I restart the laptop, screen remain unusable

2.  When screen is lagging and I try to shut down the laptop using Power button and when I hit Power button to turn on the device, I see a last picture that was  displayed on the screen, before I turned laptop off

3. Issue will disappear when laptop is being turned off for at least several hours or the whole day

4. Screen is unusable in BIOS as well, so it's a Hardware issue.

I followed steps from this article:

5. When I connect to external screen, everything working smoothly.

I wonder if it can be related to integrated graphics, since, If I'm not mistaking, external display is being directly connected to a discrete graphics card, while native display still uses integrated graphic card, right? 

I owe my laptop for around 2 years and Issue started to appear a month ago

you can see how screen glitches look like. On the video, screen is not unusable, I'm trying to move mouse, but nothing is happening
