[Bug 1426887] Re: Full screen app has a white stripe on top after switching to another window

** Description changed:

  To reproduce:
  1.) Open VLC (or SMplayer or any app in fullscreen mode).
  2.) Start watching a movie and go to fullscreen mode.
  3.) Alt+tab to another open application
  4.) Alt+tab back to VLC
  After getting back to VLC you will see a white stripe on the top of the screen as on the attached screenshot.
  
  I have tried this with other applications like Firefox and the default video player (Totem).
  They produce a slightly different symptoms as they also have a white stripe on the left of the screen besides the top, but I would bet it is the same bug.
  In Totem the white stripes are also blinking a bit.
  
  I'm attaching 2 screenshots.
  1.) After starting VLC where everything is okay.
  2.) After alt+tab ing with VLC where the white stripe is already displayed.
  
  I'm using gnome-session-flashback (gnome-panel) with metacity.
