That would support the driver being the issue. MS had plans to fix that with a later version of Windows 10 but with the other Win10 upgrading issues I have been unable to test this.
I did find a solution that works for me, but it doesn't involve MS at all, so I can't contribute anything more useful for those glued to Windows. Sorry, guys.
So what is the solution you found?
I'm not glued to windows.
In fact, I'm writing this on a machine running Linux Mint!
(I switched from windows when MS unceremoniously dropped support from the video chip on this laptop. It could not play video using windows 10. Yesterday, I watched "John Wick 2" on it without a glitch!)
Anything you have discovered will be of enormous assistance to someone! :-)
