Comment 1 for bug 1041066

Predictably, there are a lot of windows stacked above the fullscreen window (google-chrome). I can easily ignore them because they're all off-screen. But this window is still a problem:
  win 14: 3000003 1932x1212 +-6+-6, draw=Y
I have no idea what it is.

Window stack from top to topmost-fullscreen:

win 0: 14001ef gtk-window-decorator 1x1 +-100+-100, draw=Y
win 1: 14001ec gtk-window-decorator 1x1 +-100+-100, draw=n
win 2: 140019b gtk-window-decorator 1x1 +-100+-100, draw=Y
