For about 2 days now my HTC One M8 has been showing the dock mode icon on the top at random, and reloading my screen in all apps at random (kicking me back to the top of the page). I tried disabling dock mode, but I can't even find it in my apps (through the settings). Putting my phone into safe mode does nothing to prevent these things from happening, either. And yes, I've ran virus software, use original charger, have rebooted, not installed new apps, etc. Since it's happening in safe mode, too, I think it is a flaw with the phone itself.
