This is strange, as of a few days ago I started getting a black box draw around the area of the active window that currently has focus, i.e. is active. See example below of this box on the back button in Safari.
This is happening in all applications and sometimes leaves the box on the screen when the window has just been closed or when you scroll (other example below). I've not installed any new software recently. It it very annoying.
Any ideas?
