This (the empty box) might also be HTC issue, because we've tried it on One X.
TheForumTroll: What apps exactly? The problem is, that if you want to show any kind of notification, you have to provide an icon. Usually to achieve "no icon" effect, a transparent icon is provided and moved to the far right. The problem is that the system might move it only to the right of the on-going notifications and leave a gap there..
