I made a small change to the camera app to make a dirty fix for the focus rectangle.
You can download the modified app here

I know it's minor, but it bugged me.

And for those that are building, it's from ~/(your building directory)/packages/apps/Camera/src/com/androiid/camera/FocusRectangle.java
There are many ways that this could have been done, even a correct way, but that's where I did it.

 

Thanks, I fixed the link.
