I get the same result with a fresh rebuild. My Ubuntu PPA build (always
fresh clone+bootstrap) shows this behavior as well.

Dimitri's plot looks very similar to the output of my first plot. The
y-axis of the lower plot is smaller than the y-axis of the plot above.

Just found out that the error occurs every time when a new plot window
is opened, not only on fresh restart of octave as I said before. It
doesn't matter if I close the old figure or open a new one with figure(x).

  graphics_toolkit fltk
  figure
  subplot(2,1,1); plot(rand(10,1)); subplot(2,1,2); plot(rand(10,1))
  %% plot looks normal

  close all
  subplot(2,1,1); plot(rand(10,1)); subplot(2,1,2); plot(rand(10,1))
  %% the y-axis of lower plot is to small

  subplot(2,1,1); plot(rand(10,1)); subplot(2,1,2); plot(rand(10,1))
  %% both plots have small y-axis
