The burn-in protection on Venu2(s) devices with CIQ4 falsely triggers and turns off the display

I have ported several watch faces with Venu1 AOD support to the Venu2 and Venu2s devices.

My AOD modes are straight forward. I'm using a dense pattern clearing every 2nd pixel row or column on the screen alternating each minute starting with the first row/column or the second row/column.

This ensures that less than 10% of the pixels are on and no particular pixel is on for more than 1 minute.

On the Venu2 the simulator detects a screen burn-in. On the Screen Burn-In Simulation window it looks like the overlay pattern is ignored.

Also some drawing artifacts are missing on the burn-in screen for example the minute and hour hands.

I'm in contact with 2 other developers who have similar problems with at least some of their watch faces.

I already uploaded my watch faces with Venu2 support to the Connect IQ store and received feedback from a user who also owns a Venu1 that

the AOD is not working on his new Venu2. - It turns off the screen.

So this is potentially not only a problem of the simulator but also of the actual device.

Here is a screen recording of the problem in action highlighting the differences between Venu1 and Venu2:

Ok, to make this easier.

I have generated a test project that displays the issue fully. For venu, venud, venusq, venusqm it works perfectly. For venu2, venu2s, smallwearable2021 and wearable2021 I see a burn in error as soon as I toggle power mode.

I cannot either attach files or insert formatted code, so here is the view class in raw text:

Change

dc.setColor(Graphics.COLOR_WHITE,Graphics.COLOR_BLACK);

to

dc.setColor(Graphics.COLOR_BLACK,Graphics.COLOR_BLACK);

Does it then work?

You'll need to add something like:

dc.setColor(Graphics.COLOR_WHITE,Graphics.COLOR_TRANSPARENT);

before the draw text
