It is not really a bug; it is an inherent limitation in mpl's default
automatic Axes positioning. Axes positions are given in normalized
coordinates relative to the figure, so if you shrink the height of the
figure (relative to the default, for which the default positioning
parameters are designed), there is less physical space available for the
x-axis ticks, ticklabels, and label--and things can get cut off. If you
are adjusting the figsize and/or the font size, then chances are you
need to adjust these normalized coordinate Axes position parameters as
well. Trial and error is typically needed; it can be facilitated by
using the subplot adjuster widget in an interactive window (second to
last button on the toolbar) to decide what looks good. Then use the
figure.subplot.* entries in matplotlibrc, or call
plt.subplots_adjust(bottom=0.15) (for example), or call it as a method
of the figure you have just created.
For doing the interactive adjustment, you will want to use a smaller
figure dpi, something to match your screen. Everything will scale
correctly when you save the figure at higher dpi.
