problem with font size on the simulator of a Fenix 5X

Hello,

I'm working on a widget to display the forecast from the current location.

I'm targeting severals watches, and I've noticed a problem between the Fenix 3 and the Fenix 5X, at least on the simulator (I don't have access to real world watch).

I'm using the following code to display mandatories OpenWeatherMap Credits :

/* mandatory OpenWeather credits. */
dc.setColor(Graphics.COLOR_DK_GRAY, Graphics.COLOR_WHITE);
dc.drawText(width/2, dc.getHeight()-43 , Graphics.FONT_XTINY, "Powered by", Graphics.TEXT_JUSTIFY_CENTER | Graphics.TEXT_JUSTIFY_VCENTER);
dc.setColor(Graphics.COLOR_PURPLE, Graphics.COLOR_WHITE);
dc.drawText(width/2, dc.getHeight()-23 , Graphics.FONT_XTINY, "OpenWeatherMap!", Graphics.TEXT_JUSTIFY_CENTER | Graphics.TEXT_JUSTIFY_VCENTER);


On the Fenix 3, it looks like this :



On the Fenix5X, it looks like this :



What am I doing wrong ?

Thanks for your help.
