I’ve purchased a new laptop. It is an Asus Zenbook UM431D with AMD® Ryzen 5 3500u with radeon vega mobile gfx × 8 and the screen is flickering - horizontal lines on the top part of the screen - from left to right.
I’ve updated Endless and also reinstalled it as well - factory reset. The issue is constant - it is visible if watching anything on youtube.
I’ve attached the diagnostic file - diagnostic completed after the factory reset.
