I am having the same issues! Sometimes one screen goes black, sometimes both go black. then I get random distortion sometimes, little vertical flickering. I had no issues with my Surface pro 5. I thought this update would be seamless. I have double the issues
i had previously (My surface also suffers from losing wifi connection periodically. I swear it even affects devices around it that are using wifi -- sounds crazy, i know, but i never had these issues!!)
Please we need an updated GPU driver! I think this is software related...
