I am also hit by the same problem starting about a week ago. My surface pro 4 is slightly more than 1 year old. The screen flickers rapidly (shaking up and down) from 1 or 2 lines of pixel below the top, rendering images and characters blur. Slight movement
of cursor or keystroke would stop the shaking immediately, but only to have it returns 1 or 2 seconds later.
By the consistency of the symptoms, I have no doubt this is a systematic reliability issue of surface pro 4 either due to design flaw or poor quality parts, or both. I also have no doubt that the withdrawal of recommendation by Consumer Report is fully justified.
It is a shame that Microsoft is being so irresponsible, instead of addressing and acknowledging the issue, they simply resorted to marketing spin to deny the persistent quality and reliability problems.
It is fortunate that I didn't place an order for surface pro 2017, which I almost did a few weeks ago. I will never buy another product from Microsoft again.
I am not sure how much the issue is going to escalate. The shaking used to stop with slight motion of the cursor. But it seems harder and harder to stop the shaking now, in fact, the shaking seems a lot more persistent now. I am afraid I might just be seeing
the end of this SP4 very soon.
I tried to reduce the severity by installing 8GadgetPack, and activated the clock with second hand turned on and always on top, hopefully the constant refresh of the second hand position update could alleviate the shaking issue. Unfortunately it is not very
effective. In fact, no suggested solutions work at all. This is frustrating.
