It can be reproduced with the following procedure:

  1) Emacs -Q
  2) C-x 2
  3) Drag the upper mode line downward until the number of lines of
     the lower window becomes 3.
  4) M-x C-q C-j

Carbon scroll bars seem to behave strangely (i.e., display garbage
outside the "control rectangle") when it is too short.  At least,
scroll bars in Mac OS X 10.3.9 and 10.4.5 behave differently in such
cases.  I suspect that this is a bug in Carbon, but anyway, I
installed some workaround because we cannot expect that it will be
fixed for old versions.
