Comment 27 for bug 940603

All my windows have shadows. Now the computer has been on for a couple of days. It seems that is not only one white rectangle, but there are many, as the border became black, the same that happens whenever I open many windows of the same size in the same position.

I use chrome, and I'm guessing it's something related to it. My guess is google notifications. Whenever I use my computer without opening google chrome, the white box never appears (ie: my laptop). It has the same width as the google notification message box.
