[Octave-bug-tracker] [bug #55931] Plot disappears after zooming out once and then clicking "Autoscale"

[Philip Nienhuis]

Follow-up Comment #5, bug #55931 (project octave):

This is still present in 8.0.0, although much less pronounced. 
 
What I now see is that from any zoom-in or zoom-out situation, when activating
the zoom-out button and clicking twice quite rapidly in the plot, the second
click behaves as "Automatic limits for current axis". Same for the zoom-in
button.
After a few more random zoom-out clicks in the plot, the lines sometimes
disappear completely while the axes show extreme zoomed-out limits. Clicking
the "Automatic limits" doesn't help anymore then.
So careful and not-too-fast zooming helps to preserve the plot.

This makes me suspect that behind the scenes, the graphics system needs quite
a bit of time catching up and getting ready for a next user action / mouse
click ... could that be the underlying reason for the apparent improvement? -
I have much faster HW these days so that "catching up" goes much faster as
well.
