Comment 3 for bug 510073

I can confirm that. I have intermittent behaviour when it comes to taking a screenshot of the current window that includes the window borders: if the "take screenshot" window doesn't overlap the current window, it fails completely; if the "take screenshot" window overlaps the current window, it works but also includes the overlapping area of the "take screenshot" tool while fading out (see top left corner of attached screenshot).

As a result, the Alt+PrtSc shortcut only works intermittently as well.
