Yup, I get the same effect on OSX backend, in matplotlib 1.4.3 and 1.5.1. I believe this is due to the fact that the OSX backend doesn't implement the relevant animation calls - see : matplotlib/matplotlib#531

There's a new PR for matplotlib that just addressed this : matplotlib/matplotlib#6178

Yes, I get the same behavior for pyqt4 on homebrew at least. All works well for me with the TkAgg backend. @Eric89GXL - what backend were you testing on? Do you get the same problems as we do?

Linux, qt backend. Oh OSX...

More investigation : only one window updating for qt4, matplotlib 1.4.3 or 1.5.1, Python 2.7. Seems to work correctly for qt5, matplotlib 1.4.3 or 1.5.1, Python 3.5.

@matthew-brett last time I checked it worked fine over here.

Alex - what do you get with qt4 if you use IPython and start with %matplotib qt ?

matplotlib/matplotlib#5517

Hi all, is this still a problem for anybody? Using the latest OSX, I was able to run img.orthoview() and move around quite easily.
