Comment 3 for bug 1052682

I don't habe a 100%-sure way to reproduce it, but the following reproduces the issue very soon almost surely for me:

- have several windows open, for example: Google Chrome, Thunderbird, a Terminal, a Nautilus window.
- have some of them maximized and some of them not
- resize one of them to a not-too-big size, e.g. about half the dimensions of the screen

- now click on the title bar of this window and drag it around for a while. From time to time stop moving the cursor (without releasing the button) and then start moving again, sometimes slowly, sometimes less slowly, as if "looking for" some spot where it will stick. Soon you will find one.
