Screen flickers after laptop is on for a while

[mejiro808]

I have an HP Spectre x360 15" notebook. When I first start up the laptop, the screen is perfectly fine but after being on for a couple of hours, faint vertical lines start appearing and then after a while it starts to flicker very badly, like a strobe light with moving vertical lines. The picture also shifts up and down horizontally. At this point there's nothing I can do but turn it off. The next day when I turn it on, it is fine again, but quality deteriorates the longer the screen is left on. 

Using an external monitor, the picture has no problem.

I've tried running the system diagnostic (no issues found). I updated the drivers on both onboard and dedicated graphics card (Intel HD Graphics 630 & Radion RX Vega M GL). 

Any ideas what else I can try? It started doing this a little after the 1 year warranty expired.

Thanks in advance to any advice?

Thank you for the update.

In that case, I would suggest you perform the system reset and check.
