Thanks hedgetrimmer - what you say makes sense..
It is like there exists a hardware issue that software needs to correct or take account of sometimes it does other times not - but when the fix does come along then it is a firmware change as the hardware stays the same.
Brief update on Pixelation problem.
Today I was messing around with Magnetic Interference and compass deviations. Part of testing required CS-Ub, RC to be powed on, MPP read to fly, and GO-4 app running.
As part of that part, I had to pickup and move MPP, then set MPP back down. During the testing I noticed that setting MPP down would result in Pixelation at bottom part of Liveview screen being displayed on CS-Ub.
That would point to MPP being sensitive to vibrations. In that picking up MPP would induce very little vibration. Where as setting MPP down would induce minor vibrations.
Nothing of course like vibration form say a 4-inch (or higher) drop would.
For moment assuming Pixelation problem is caused by vibrations to MPP, then I (perhaps we) are looking at possible broken wire, cracked solder joint, or split foil run (aka Hardware).
Since my MPP is under warranty, it may soon be headed off to DJI.
If it were not under warranty, and I could find some information as to what board / board area handles Downscaling, Liveview compression, and transmission - I would be opening MPP up and looking for vibration senstive spot. Granted a split foil run could be problematic if DJI's boards are multi-layer, and split is on a sub-layer.
