I'm rather happy my moms Turion 2 laptop is still running Windows 10 happily and it's easily far better than any previous Windows. Score one for a decent video chip
(Also unsupported, but the machine does still work surprisingly well for modern casual usage...just painful to update.)
Anyway, I think I was just having that happen on my brothers Atom (Bay Trail) machine so yeah I can see how it'd irritate you, but I got the latest Intel graphics drivers on it and it's fine now.
(Was working on all three of his machines at once just for the hell of it.)
(If only the dumb thing had enough space to actually get the latest version of W10 on. Working on it, kinda. He just died so not really feeling the need.)
