BUG: Venu 2 display somehow shifted on real device, working ok in sim

I'm working on adding HR Zone & candence graphics to my Data Field App. It works perfect on my Epix 2, FR245M and my other devices.

BUT: on Venu 2 it looks as if the whole screen in shifted few pixels both down and left. This is in 1 field layout mode. Which makes my App looks really strange.

I'll attach a picture for how it looks in real life and one for sim.

    Ok, all good then. I can design my data field App so it only uses the "always guaranteedd visible" part of the display, which will be the inner part of the circular display then. But I need to know what specs to design from.

    As far as I can tell on my own Venu 2, what I draw on the display is shiftet around (lef, right, down) randomly up to max 10 pixels. So, if I do not use the outer 10 pixels of the round display, I do not risk drawing stuff that sometimes is not visible.

    Am I correct that it is max 10 pixels?
    I assume this is for all types of field layouts that the entire display is shifted around?

    Also, importantly, this type of burn in protection, is that also implemented for the other AMOLED devices:
    + Venu 2 Plus / D2 Air X10 ?
    + Venu 2S?
    + Venu / Venu Mercedes-Benz Collection / D2 Air ?
    + Venu SQ (M) ?
    + Venu SQ2 (M) ?

    And, if so, is it also for these up to 10 pixels?

    This is a built-in protection feature on the Venu 2 devices. So shifting data fields will happen to prevent burn-in.

    Garmin, please comment - is this a feature or a bug? And, if a feature, then on which devices and according to what spec?

    Sorry FlowState, I had completely forgotten that discussion on the Epix lines!!

    I can be proven wrong of cause, but I don't believe still that Garmin are moving around the "native" lines at random to prevent burn in on Epix. I have been playing around (again) with Epix in those layouts where Garmin draw these lines - and they seem always to draw them at the same place vs the data field boundaries. So, no random behaviour as far as I can tell. And, Garmin have also acknowledged that it is a defect on Epix. Furthermore, in my latest version of the App - with the HR color meters - the screen on my Epix looks exactly in real life like it does in Sim.

    It's on Venu2 the entire screen seem to be shifted quite a bit - clearly visible - on real life vs sim. And. btw, not always same way on my Venu2, so their seem to be some random shifting going on. Making your point that this is by design very likely! I just wish Garmin would confirm (or not) and document what exactly is going on, e.g. how much do they shift around, when, and on which devices. My user experience suck right now - but if I just knew what they are doing I can design around it. E.g. use less of the screen somehow.

    Garmin, PLEASE comment!?

    But I typed a huge comment about how the horizontal and vertical dividing lines were shifting on your Epix 2, based on the screenshots you provided, and you responded to it:

    Isn't it possible that the watch is also shifting other parts of the screen? That would make sense if the goal is to prevent screen burn-in.
