Hi,

Thanks for your report. Can you provide a minimal script that triggers the crash when zooming so that we can test?

I tested the following


for ii = 1:6
  suplot (6,1,ii)
  plot (1:1e5)
endfor


and when when I click to start drawing the zoom-box I can see that the backgroud axes change aspect, some axes lines are missing. Then when I release the button the plot in the corresponding axes is is correctly rescaled but some axes lines are still missing. Then I have to force a redraw of the figure (by switching to another window and back for example) to se the figure redrawn correctly.

So no crash for me on linux but a very weird behavior.

I had my script produce a subplot and maybe the background memory is low I am not sure as I have a few applications running and my data as you can see is many points. The subplot window when I zoomed in after the second time crashed.
Not sure why or what caused this.


I wanted to check for similar bugs but was not sure exactly how to refine my search lest this is a duplicate.
Also how do I search with key words for bugs in savannah because the annoying thing is also that when you are searching for bugs it is not obvious how to focus on the specific project and then within that project go into a key word search eliminating irrelevant bugs.
The only option is the text in the search, then in projects then press search but other than that nothing. Any tips

I am using windows 10.
