HI Joseph, please see below:
• Just to verify, can everyone confirm if all have installed the Creators Update?
Yes, it is installed. Latest Windows Updates as well.
• When you turn on the Surface, did you notice if the Surface logo flickers/shakes as well?
Yes, but only if the device has already started exhibiting the issue. It typically does not happen from a cold boot
• Does it occurs immediately after you logged in to Windows, or when working on a certain task? If so, how long does flickering/shaking last?
If I connect to a second display it can take < 30 mins. It will continue for the rest of my working day. If I moving content it will stop shaking the screen, but a couple of times the shaking has been so severe that this does not help.
• Does your device connect to your external monitor/s via Surface docking station when this occurs?
Yes via external docking state, though it does also happen with the built in mini-display adapter and when not connected to a second monitor.
• Are you using a splitter/adapter to connect directly to an external monitor without the docking station?
I have before as with the bullet point.
Hope this helps, if you want direct contact with me let me know so it can be arranged.
Luke
