I am experiencing blue shadows to the right of objects on my screen, but only some objects. For instance, all of this text has the shadows, as does my cursor over the text box and interactive objects on wepages, but my background image on my desktop and my cursor when over any part of my desktop are not shadowed. File folders and the like do not have the shadows, whereas they seem to appear in all applications. (I just tested pdfs and paint, they've both got the shadows next to all dark spots.) Any ideas? I don't even know where to start. First noticed this after a restart a few hours ago.
