  compiz eats mouse clicks at the border of the screen

Bug description:
  Binary package hint: compiz

  If you have a maximized Firefox window, throwing your mouse to the
  right usually lets you scroll, due to Fitt's law.  However, with
  compiz or beryl enabled, it breaks Fitt's law because for some reason
  it reserves a pixel of space on the full right and left edges of the
  screen (not just the corner four hot spots that it uses for Expose-
  like stuff).

  Also, if you have your panel oriented to the left or right, you run
  into this same problem, where you can't access menus by throwing your
  mouse to where the menu is; compiz again reserves space along the full
  length of the left/right edges of the screen.

  I usually use my web browser in an unmaximized state but move it so
  that the scrollbar is just falling off the edge of the screen, so that
  I can flick my mouse to the right and use the scroll bar easily.  This
  works in all OS's window managers, from OS X to XP to Fluxbox to Gnome
  and KDE.

  However, with compiz enabled, moving my mouse to the very left or
  right of the screen (for scrollbars) makes it look like it's not
  focusing on the object.  I think this has something to do with how
  AIGLX reserves space outside the desktop for buffering, or something
  like that.

  This doesn't affect the top or corners of the screen however (plus the
  corners are reserved for things like Expose, which is fine)--only the
  left and right edges with compiz don't obey Fitt's law.
