As to the OS you can't trust Microsoft for the driver. Go get it from the maker next time to test if it's driver related. This does sound like driver or hardware.
Using Windows 10 laptop, ver1803,BUILD1734.590
When booting up after overnight power off, but also through the day the taskbar expands upward and vibrates. It occurs spontaneously and may last many minutes or hours.
It Iis transparent and pixilated or exhibits a netlike structure. It may cover a small strip or 30% of the screen. I have uninstalled and re-upped display drivers without effect.
I will greatly appreciate advice.
