[Linux] Application doesn't work properly with OS scaling and Starling

[pol2095]

Hello,

Thanks for the new AIR SDK 51.3.3.2 release, I still have the same issue with Starling on a 4K screen, though it's fixed when using the classic displayList.

Thanks

Do you have any information on how to reproduce this issue? What Stage3D settings are you using?

classic displayList :

package
{
	import flash.display.Bitmap;
	import flash.display.Sprite;
	import flash.display.StageAlign;
	import flash.display.StageScaleMode;
	import flash.events.Event;
	
	public class Main extends Sprite
	{
		[Embed(source = './Starling-flying.png')]
		private var MyImageClass:Class;
		private var myImage:Bitmap = new MyImageClass();
		
		public function Main()
		{
			this.addEventListener(Event.ADDED_TO_STAGE, addedToStageHandler);
		}
		
		private function addedToStageHandler(event:Event):void
		{
			this.removeEventListener(Event.ADDED_TO_STAGE, addedToStageHandler);
			stage.scaleMode = StageScaleMode.NO_SCALE;
			stage.align = StageAlign.TOP_LEFT;
			
			this.addChild(myImage);
		}
	}
}

Starling :

package{
	import com.ImageStarling;
	
	import flash.display.Sprite;
	import flash.events.Event;
	import flash.display.StageAlign;
	import flash.display.StageScaleMode;
	
	import starling.core.Starling;
	
	public class Main extends Sprite
	{	
		private var _starling:Starling = null;
		
		public function Main()
		{
			stage.scaleMode = StageScaleMode.NO_SCALE;
			stage.align = StageAlign.TOP_LEFT;
			addEventListener(Event.ADDED_TO_STAGE, init);
		}
		
		public function init(event:Event):void
		{
			removeEventListener(Event.ADDED_TO_STAGE, init);
			_starling = new Starling(ImageStarling, stage);
			_starling.supportHighResolutions = true;
			_starling.start();
		}
	}
}

package com
{
	import flash.display.Bitmap;
	import starling.display.Image;
	import starling.textures.Texture;
	import starling.events.Event;
	import starling.display.Sprite;
	
	public class ImageStarling extends Sprite
	{ 
		[Embed(source = "../Starling-flying.png")]
		private static const MyImageClass:Class;
		private var myImage:Bitmap = new MyImageClass();
		
		public function ImageStarling()
		{
			addEventListener(Event.ADDED_TO_STAGE, init);
		}
		
		private function init(event:Event):void
		{
			removeEventListener(Event.ADDED_TO_STAGE, init);
			
			var texture: Texture = Texture.fromBitmap(myImage);
			var image:Image = new Image( texture );
			
			this.addChild(image);
		}
	}
}

and the image

Thanks for that, what about your app descriptor? Are you setting the requestedDisplayResolution?
