------------------------------------
Summary: Shapes with Transparent fills hide underlying shapes
Key: FLEX-33446
URL: https://issues.apache.org/jira/browse/FLEX-33446
Project: Apache Flex
Issue Type: Bug
Components: .Unspecified - Framework
Affects Versions: Adobe Flex SDK 4.6 (Release)
Environment: Windows XP 64
Firefox 19.0.2
Reporter: john kyritses
Priority: Minor
Draw 22 red rectangles (with 0-alpha fills and solid red line style) over green
rectangle (with green fill) hides the green rectangle where it intersects with
all 22 red rectangles.
The green rectangle is displayed correctly if there are only 21 red rectangles
over it.
protected function drawGreenSquare():void {
// draw green box
var square:Shape = new Shape();
square.graphics.beginFill(0x00FF00, 0.5);
square.graphics.drawRect(100, 100, 500, 500);
square.graphics.endFill();
var uiC:UIComponent = new UIComponent();
uiC.addChild(square);
canvas.addElement(uiC);
}
protected function drawRedSquares():void {
// CHANGING THE LIMIT TO 22 DOES NOT TRIGGER THE BUG
const limit:int = 23;
const offsetScale:int = 4;
// add red squares
var square:Shape = new Shape();
for ( var i:int=-10; i<limit-10;i++ ) {
var offsetX:int = 100 + ( i * offsetScale );
var offsetY:int = 100 + ( i * offsetScale );
square.graphics.lineStyle(2,0xFF0000,1.);
square.graphics.beginFill(0xFF0000, 0.0);
square.graphics.drawRect(offsetX, offsetY, 200, 200);
