[Platform_Windows]Device font looks different in Flash player & AIR


Problem Description:
I've tried to display white text on a colored background in FlashPlayer & AIR runtime. Unfortunately, the text displayed in the AIR runtime looks much worse, than FlashPlayer one.

Steps to Reproduce:
Compile & run following code in Flash Player and Air.

main.xml file (on AIR, use s:WindowedApplication instead of s:Application)
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx=""
xmlns:mx="library://" minWidth="955" minHeight="600">
<fx:Style source="style.css" />
<s:Label text="() sample text ()" styleName="test" />

/* style.css CSS file */
@namespace s "library://";
@namespace mx "library://";
.test {
font-family: Arial;
font-size: 10;
font-weight: bold;
color: white;

background-color: #BC2C49;

Actual Result:
The label displays much worse on AIR. You can see on the attached image (AIR version at top, Flash version at bottom).

Expected Result:
Label on AIR should display exactly the same as in Flash Player.

Any Workarounds:
Unfortunately no :-( Maybe embed fonts would do, but I don't want to embed.

    I've made a simple workaround (see, based on fact, that font is drawn properly on bitmap.

    The font in AIR environment looks exactly the same like the same one in FlashPlayer, but with cacheAsBitmap = true.

    Hi, I've added with two projects (the code is nearly the same as provided above).
