I'm having same problem...again. This time I keep getting an unknown window flashing on my screen reportedly and it started Thursday or Friday (~ 4/3/20). Tried the troubleshooting, update, new drivers, uninstall, reinstall...still happens.
I say AGAIN b/c last July I had the "known issue " of garbking across the bottom of my SP4 at 2.5 yrs and I use this machine every day, all day for my work (at home). After a few hours on phone, they finally agreed to let me go to Microsoft store in my
area & trade it in for a new one.
Had to get special permission & explain again at store but in end they gave me a "new" one or so I thought. They said they didn't have an SP4 so have me the upgraded 6 with same "guts". Since this new occurrence, in looking at the Version, it says SP4!!!
Why would they give me same thing? Nine years months later...same thing. Pandemic has store closed and now will fight on phone to get a new one. Again.
WAY WAY too expensive for this to happen. And I LOVE my Surface Pro. Their problem has become MY problem twice.
Not happy. Good luck to us all.
