Lumia 800 - Strange UI Behavior after Touch!!!

Question

When moving my finger horizontally or vertically (more noticeable when vertically scrolling) and leaving my finger on the screen after the move, the UI begins to shake up and down or side to side depending on whether I moved the UI vertically or horizontally. I found this when playing assassins creed first, the virtual joy stick under my thumb was moving on its own when my thumb was still. Trying this on the start screen by scrolling up or down a little and leaving my finger on the screen presented me with the UI moving on its own.
This is quite frustrating especially in game that require me to leave my finger/thumb on the screen. This behavior is noticeable in all elements for me, menus, internet browser, all hubs and so on. If you want to try it on your devices let me know if you have experienced the same thing. Remember just go to the start screen, scroll up or down slightly and don't take your finger off the screen, after a second or two the UI may start moving on its own like it does with me.
If there is anyway to reset the screen calibration through diagnostics apps or anything let me know please.
I have uploaded a video, its pretty poor quality but if you watch the calendar tile whilst I keep my finger still you will see how the UI moves on its own. More noticeable when you see it in person. http://youtu.be/vaJGcN7UfoE

It doesn't do that on mine Lumia, and I have put mine of my desk keeping my fingers steady after scrolling. Usually capacitive screens, and especially amoled ones are quite sensitive, and from looking at your video where you hold the phone in one hand up in front of cam and touches it with your other hand while the device is shaking like crazy doesn't make it easy to actually know if it's your or the device.
I guess you of course have done this already, but if not lay it down on a desk or table. Hold it tight with one hand and do the scrolling with your other hand. Then make sure the phone is dead still and so with your finger. Does it still do it?
I haven't found a setting or way to calibrate the screen. And it might only be my ignorance, but I haven't seen any setting or so regarding calibrating screen on any on my previous devices - I guess I have had 6-8 phones with capacitive displays.
I know that at least some of the s60 Nokia devices with resistive screen had it, but that's something else.
