Yes, I'm the winner...
In the last weeks I did some work with Matplotlib as I want to ship some 
examples with wxGlade. As I had experience from wxGlade with fixing 
crashes and redraw errors, it seemed natural to contribute to Matplotlib.

For a 3.0 release, I will certainly look into making the Wx backends 
more straightforward, similar the double-buffering example from the 
wxPython demo or doc.
Also, for 3.0 it would probably make sense to move from ClientDC to 
Refresh/PaintDC, as this would allow to unify the rubberband code 
between OS X and the rest again.

For 2.2 this would have been too risky.

The bug actually looks like a wx bug as Classic 3.0.2 is working. It 
would be nice if it could be addressed as Wayland is becoming mainstream 
now. If not, then the wxPython demo needs some work as the 
ScrolledWindow demo fails as well.
