[Bug 611886] Re: maximized windows don't get redrawn


** Description changed:

  Binary package hint: xserver-xorg
  Practically every time I plug in an external monitor and set up dual-
  head (1280x1024 external LCD connected over analog VGA to the right of
  my primary laptop screen, 1280x800), maximized windows stop being
  redrawn.  I've seen this happen with xchat-gnome and chromium windows,
  and even gnome-panel once or twice. The window content is drawn
  correctly, but shows an outdated picture that doesn't represent the
  current state.  For example, scrolling, going back in history or opening
  a new tab in chromium appears to have no effect; applets added to a
  newly created panel aren't shown.
  There's a workaround: unmaximize the window and maximize it again.  The
  window gets redrawn correctly and doesn't get frozen again.  For gnome-
  panel the workaround is to open its properties and check/uncheck "Show
  hide buttons".
