I am using Jetpack 2.0.2 on wordpress 3.4.2 on my website Aero-Sapiens.
I also cusotmized the widget as per instructions in this post so as to have theme background as the background of widget and it worked seamlessly.
Now it works perfect till I am not logged in Facebook (in any other tab of browser). As soon as I log into Facebook (in any other browser tab) or login to my site using Facebook, the height of the widget gets reduced and also the background changes as per colour scheme of widget (Default - Light).
Any suggestions to fix it will be highly appreciated.
