Pixel 3 XL screen cut off (portrait mode)

I'm starting a new thread because there have already been different suggestion to solve this problem, but none is actually working on the Pixel 3 XL.

On the Pixel 3 XL in portrait mode there is a black bar at the top of the screen, so the stage starts lower (80 pixels), which results in the bottom part of the screen being cut off.

I'm using latest Air 31

In my application XML:

<meta-data android:name="android.max_aspect" android:value="2.16" />

...

<fullScreen>true</fullScreen>

In the code:

stage.align = StageAlign.TOP_LEFT;

stage.scaleMode = StageScaleMode.NO_SCALE;

There is no resizing happening during startup, as some solution suggested to listen for RESIZE events, but the stage.fullScreenHeight stays the same.

The problem is not solved with different android.max_aspect values.

The only way I can get the screen fullscreen is by using:

stage.displayState = StageDisplayState.NORMAL;

but then the top and bottom part is behind transparent system bars.

I would love to hear a solution that works on a Pixel 3 XL.

(if you think you have a solution, but no access to a Pixel 3 XL, I can test your apk)
