Surface Pro 4 Screen Shaking/Shuddering up and down while Idle

I have the same issue.  I strongly suspect overheating. 

It's been intermittent for me and usually stops when I interact with it.  However, today after a lot of video processing over a couple hours, it's shaking into a constant blur and won't stop at all.  When I stop the video process for a while (i.e., minimize the app), it will stop.  It will stop more quickly if I place my hands on the top/back of it, which feels notably hot, but not burn you hot (i.e., probably 60C, but I don't have a temperature monitor for the CPU, nor do I know that it's CPU temperature necessarily).  Touching it will conduct heat away faster than ambient air, so I believe I'm effectively cooling it faster by holding the back of it.  I started blowing on the back as well, it would cool and then heat up, stop shaking and then start again, repeat until it finally cooled. 

I've repeated this about 4 times consistently by maximizing and minimizing a video application.  Not terribly scientific, but I think it's an overheating issue with one of the components.  Could be video processor, cpu, memory, or the display itself.  I don't know, but I'd bet it's more related to video/gfx processing or the display since I minimized rather than closed the video application.  So if the memory and cpu usage remained about the same, and the shaking would start and stop based on video/gfx processing, that provides a pointer.

Anyway, try some form of external cooling

Why, so we can replace our Surface Pro 4's for the fourth time with another "refurbished" one that'll break down in weeks? Because that's what it looks like I'll have to do. 

My first one crashed whenever I touched the screen. My second one bricked itself through windows updates, my third one had unacceptable levels of light bleed, and now my fourth one has the shakes. I managed to fix the shakes for a bit by using the seconds timer in the task bar. But then Microsoft found a fix for my problem by disabling that fix and now the shaking is uncontrollable. Thanks for that, your customers put in the effort to find fixes and spread awareness of those fixes more than you do. 

So STOP it with your stock "have you tried our software troubleshooting" responses and make an official statement already. This premium priced product is a mess and you know it. Fix it.

Well I have followed a workaround that someone discovered in this thread about possibly the same issue:

https://answers.microsoft.com/en-us/surface/forum/surfpro4-surfdrivers/surface-pro-4-screen-flickers/e431e3c8-ced5-4ed7-b208-eda8c72aa313

Adding seconds to the clock in the taskbar seems to have stop the issue for me (for the time being) as the display now has to refresh itself every second so isn't idle (like watching a film).

The workaround is working well, but I'd still much rather a proper fix!

I was told that " screen shaking is *usually* a phantom touch problem.  An easy way to test for this is to bring up an app like paint and full-screen it, then see if the device is registering touch inputs periodically.

If it is a phantom touch problem, you can try the steps here:  https://support.microsoft.com/en-US/help/3165497 "

Keep us posted.

If the "screen shaking" is really caused by a phantom touch problem, then logically, disabling the 3 touch devices as indicated below should eliminate "screen shake".

SOLVED

This is absolutely a hardware issue.  I took the surface into the Microsoft Store.  They took one look at it, noticed the screen flickered on boot up, and swapped it with an old one.  If you're under warranty its a swap out.  If you're not, it's expensive.

IF YOUR SCREEN IS FLICKERING.  RESTART.  IF THE FLICKER CONTINUES DURING THE ENTIRE BOOT UP PROCESS, THIS IS 100% HARDWARE ISSUE AND YOU MUST TAKE IT IN.
