[Mac] Map changes resolution when moved to secondary screen about mapsui HOT 2 CLOSED

Thanks for you clear bug report. What you describe seems like a problem with PixelDensity. It may not be a Mac specific problem but a problem that shows if you work with two monitors with a different density. You can request the density in the MainPage of you app with:

var pixelDensity = XamlRoot?.RasterizationScale;

Could you check that? Perhaps you need to start the app in a specific screen to get a correct value.

I am testing on Windows and can not reproduce it there, but that may be because of my monitors.

Looking at our code just now I think it is more likely that this is a bug in SkiaSharp or Uno. We do not store the PixelDensity but request it on every iteration. I don't know what else we could do to fix this.

I also found another problem and that is that the mouse wheel event is not fired on my second monitor unless I have the pointer near the top left (it seems 1/16th of the screen area).

@pauldendulk. I checked the pixiel density and doesn't seem to change when switching screens, as it does on windows (just tested on both platforms). I'll raise an issue to UNO. Thanks for your help!
