I have two images of scene for 2.2.0b06 and 2.1.1b02. They are different for this build.

One as a result of launching application on 2.1.1b02 and one on 2.2.0b06. d3d rendering.
There is a diff between them - for center and right alignment text moved on 1 pixel. That is shown on the diff:

and that is original image:

I couldn't reproduce this in separate application, so use:

hg clone http://shaman.russia.sun.com/hg/index.cgi/java-client
add build.properties file in java-client folder with the next content:
javafx.home=C\:/work/builds/2.2.0b06x64/javafx-sdk2.2.0-beta <-path to javafx sdk
Open controls tests suite.
Run class
javafx.scene.control.test.labeleds.CheckBoxApp
or any other from the same package.
Navigate to labeleds, setTextAlignment.

Also, look at ShiftedText.jpg. I've showed place, where shifting and color changing is notable. There is a left-right movement.
