Quick test with oscilloscope would most likely show how much noise there is. Few extra caps on the power lines could fix it.

I trust that you've read this and updated to the most recent release version of ubuntu ?

Yes sir. Screen flicker got fixed with that but not the noise on screen. (random pixels flickering) If the older batches didn't have these problems then it might be that the displays have some sort of issue. Either with filtering on the power lines or signal.
