On my surface 3, windows 10, windows 7 style, since the last few updates to classic shell. when I first wake it up from hibernate, sometimes but not always, it will start to cycle through showing the start menu as if I clicked on it or the side button. sometimes it's a few times, sometimes it's on steroids. it will stop after a few minutes. never does it after sleep mode, only after hibernation. doesn't matter what program I'm using (game, app, word, etc.), the menu pops up. sometimes it flashes back and forth between showing and not showing, sometimes it shows and I tap the screen and it goes away, then will show up again. I've uninstalled and reinstalled, etc. again, only after being in hibernation, not after sleep mode.
