Yes we just exposed cool features, I am not surprised that it also exposes nasty bugs :-).

I can also reproduce this behaviour with Octave 4.2.1 when manually resizing the figure from the following commands:

So this is no recent regression.
Also there is this intermittent zooming out effect when using the manual rotate function in the figure. This is more profound when rotating at high and low elevations. When rotating with the camera at z approximately 0 the effect doesn't show.
There might be something wrong in update_camera in graphics.cc.

The title says it all. I observe that in the process of printing, which involves resizing the figure, the printed axes generally appears like "unzoomed".

Try "demo camva". Resizing manually the figure (by dragging a corner with the mouse) makes the size of the axes jump from large (larger than the figure) to small.
