I am parenting a text with box graphic background with a static position.

The text aligned right and the background starts with the text but the text is not static it adjust it's position what ever the text characters are! I mean it moves pixels in different random directions.

Aligning the text left is OK but not the right aligned text.

Try to write "dfdfdf" in the text tool and align the text to right and start edit the text by writing "dfdfdfdfdf" and see.
