Details:

(I have some reminiscence of this having been reported earlier but I couldn't
find reports about it in the bug tracker. Sorry if this is a duplicate.)

Redrawing plotyy plots result in clobbered-up plots.
For OpenGL and gnuplot the problems appear to be differently but I don't know
if they are really different bugs.

Steps to reproduce:

(OpenGL)
demo plotyy
## Then stretch plot to make it wider, and click "Autoscale" button
==> result for OpenGL in first pic plotyy_x-axis_bug_OpenGL.png
The tick marks for the two X-axes are different and don't coincide.
Expected result: same X-axis tick positions for both subplots of plotyy

(Gnuplot)
demo plotyy
## Stretch plot to make it wider, press "redraw" button
==> result for Gnuplot is in plotyy_x-axis_bug_gnuplot.png
There the entire plot is partly redrawn, only the "right side" subplot is
redrawn.
