I am now using pretest texLive 2013 to test and use the new features in xetex. However, when I use bidi & eso-pic together the page layout is broken. There is a big white space in the right side of the page. Since wallpaper package uses eso-pic & polyglossia uses bidi package, the problem occurs whenever they are used together.
I used ubuntu 12.04 packages before I use texlive 2013 and the problem didn't exit. So I decided to delete texlive 2013's bidi folder and replace it with bidi folder that comes with ubuntu packages but this did not help. I am thinking that this problem may not related to bidi package and it may be a bug in xetex. I am not tex expert and I am looking forward to your help. Please have a look to the attached example file.
