Instinct 2 screen dimensions possibly wrong on the simulator

Hi,

I have raised a question on the Discussion forum regarding the area available for drawing a data field on the Instinct 2 family. The full thread is available here: https://forums.garmin.com/developer/connect-iq/f/discussion/401206/how-to-handle-the-instinct-2-screen/1885985#1885985

Basically, I ran a test in order to get the screen dimensions of the I2 base model and compared the results with the reference page. While the reference page says its dimensions are 176 x 176, the dc.getWidth and dc.getHeight return 112 x 71. Also, on the original thread, it was noted that the onLayout seems to be called twice when only one was expected.

As a consequence, the area available for drawing is reduced:

The same code on I3, for example, works as expected:

The code is the following:

screenWidth = dc.getWidth();

screenHeight = dc.getHeight();

screenLines = [

            // Horizontal lines

            [0, screenHeight/4, screenWidth, screenHeight/4],

            [0, 2*(screenHeight/4), screenWidth, 2*(screenHeight/4)],

            [0, 3*(screenHeight/4), screenWidth, 3*(screenHeight/4)],

            // Vertical lines

            [screenWidth/2, 2*(screenHeight/8), screenWidth/2, 6*(screenHeight/8)]

        ];

and eventually I use dc.drawLine to draw the lines.

So, is this some kind of bug on the simulator? Does this also happen on real devices?

    Also, the device reference guide for Instinct 2 shows the same thing as the simulator, for 1-field and 2-field layouts.

    https://developer.garmin.com/connect-iq/reference-guides/devices-reference/#instinct%C2%AE2solardualpowerd%C4%93zledition

    i.e.

    - 1-field layout exists (according to the doc), and is just a small field in the upper left hand corner
    - 2-field layout is: 1 field with the entire screen, and 1 field with the subscreen. (Note that this is not 100% clear from the diagram)

    Similarly, the behavior of instinct3solar45mm in the sim for 1 and 2-field layouts matches the doc:

    i.e.

    - 1 field layout is the whole screen

    - 2 field layout is small field in upper left hand corner, and wide field in bottom half, both excluding the subscreen. Again this is not super clear from the diagram.
