Comment 1 for bug 226470

Managed to grab a couple of screenshots. Note the ad banner image (which is an
iframe) that has turned up in the wrong place, its own window. Also, the
blue-ish box in the middle of the page is my desktop background image hanging
around from a workspace change:

Right after that, reloading the page made it even worse. Now both the iframe of
the banner and the frame of the whole tab got ripped out. Note how the window
covers the toolbar of the "real" firefox window, and the "Screen Shot" window
showing through the firefox window is actually the first screenshot, which again
is on a different workspace. That area isnt updated at all - dragging a window
across it creates a "trail".
