I just received my brand new x17 R1, I turned it on,  got to the main screen and click on apps and other programs and the screen will go black with lines in it and then return to normal, then when I click on any app or programs it does it again as well as a slight shift of the wallpaper then it corrects itself. I have updated drivers ect, and it still does it, however when I lower the screen resolution,  I have no issues, the resolution was a factory setting to. I'll link a video of it. [URL] [IMAGE]
